SeaMonkey Meeting Details


  • Who's taking minutes? -> frg
  • Nominees for Friends of the Fish Tank:
    • WG9s and ewong for builds and infrastructure

Action Items

(who needs to do what that hasn't been recorded in a bug) We should assign people to the open items.



  • The project areas on the website need further updates to reflect the current responsibilities after some long time developers and maintainers left the project. bug 1356106 has already been filed.
  • Planning the future of SeaMonkey with a new infrastructure is in progress.
    • The documentation on the website needs to be updated for recent build config changes. frg can support anyone who wants to do this.
    • ewong started thinking about the servers needed for hosting releases and builds.
      • We are unsure how much traffic we need. WG9s might be able to help out initially with hosting builds.
    • IanN and frg do de-mozilla website changes in bug 1515507.
  • daniel mentioned that Azure Pipelines (build agent) is now free to use and also included free build time for Open Source projects.
    • ewong will look into it. It might be useful in the future to save us money. Currently we first set up Jenkins.
    • ewong has been looking at Kallithea, RhodeCode and other similar tools which are needed later to automate source code management for non mozilla repos (tools, website and others).
  • daniel asked if there are any plans to provide github repos to attract new developers.
    • frg mentioned that currently this is not planned and might not be on the agenda in the forseeable future because of existing developer shortages.
    • Mozilla does this to a degree and we don't rule it out in the future. See Mozilla gecko-dev repo as an example.


  • We are now on freenode SeaMonkey freenode irc group
    • Mozilla plans to shut down its irc presence. When the time comes we need to evaluate the possible options.
      • Slack is being discussed but no decision has been made yet.
      • One option would be to set up a project on freenode.
  • Currently there are no plans to change course. The 2.49.x line on ESR52 will be discontinued after the next release. Further updates will be done for 2.53 and up only.
    • Tobin proposed that we move from Gecko to UXP (Backend for Palemoon among other applications).
      • The team currently does not want to go this way for personal and perceived technical reasons. We invested considerable time and resources going towards a SeaMonkey release based on Gecko 60. 2.53 based on Gecko 56 is already stable and incorporating ports up to Gecko 68.
      • A SeaMonkey based on ESR 68 is also not on the horizon.
      • Given current developer resources we will do it one step as a time. Goal is to have a working infrastructure and a SeaMonkey 2.57 release for which backports will be done.

Status of the SeaMonkey Infrastructure

  • We are building up a new infrastructure using Azure.
    • The builders on the new infrastructure have been set up for local building.
    • Windows, Linux and macOS Test builds have been done.
    • Jenkins will be set up on the builders in parallel to not delay further releases.
  • Please see Infrastructure Status
  • daniel wants to contact ewong and asking about our Azure configuration.
    • If the build VMs are powered down when not in use we should save money.

Fixed Infrastructure Stuff Since Last Meeting

  • Great progress has been made.
    • IanN and frg now have access to both Azure and the infrastructure. They plan to help ewong.
      • mcsmurf will need to give them more access rights for the Azure vms.
    • Again overall not much progress has been made.
    • Building 2.49.5 is delayed because of this.

Status of the SeaMonkey Source Tree

  • Starting with ESR60 2.57 all builds need to switch to mozilla as topsourcedir. Support for comm-central and comm-esr60 as top source dir is no longer supported.
    • Do not expect to use any 2.58+ release yet other than for checking if it builds. They are fundamentally broken by Mozilla source and api removals. We are currently fixing up 2.57 in the ESR60 repo right now and will tackle this later. Bugs for the 2.57 release will also land in comm-central.
  • [comm-central]:
    • Windows, macOS and Linux builds.
    • Do not use the comm-central release.
    • The installer still works...
    • l10n is broken in comm-central because of search plugin issues. If we switch to search/list.json then we need to keep the l10n searchplugin xml files for esr60 or switch esr60 too.
    • There is more and more needed api and source support taken out of mozilla-central. It is unclear if we will ever be able to use this repo again.
    • We keep it at least building as long as we can.
    • New builds tools are needed to compile comm-central. Latest addition is nasm which will replace the unmaintained yasm.
    • See bug 1452448 for current comm-central breakages. This is not up to date.
    • msvc VS2017 is no longer supported for building under Windows. It still needs to be installed but clang-cl is used as the compiler.
    • Rust 1.33 is now mandatory.
    • Fix for bug 1300198 will unbreak the comm-central l10n builds.
  • [comm-beta]:
    • We currently do not track nor update comm-beta.
    • Do not use any current comm-beta based release.
    • See bug 1452448 for current comm-central breakages.
  • [comm-release]:
    • We currently do not track nor update comm-release.
    • Do not use any current comm-release based release.
    • An updated unofficial 2.53 is available from WG9's website. We accept filing bugs against it but it is only provided for testing purposes on the way to 2.57.
    • See bug 1379370 for current 2.53 breakages. All known major bugs for 2.53 are closed.
  • [comm-esr60]:
    • Sidebar, Help and Mail/News are broken because of XUL template removals. See bug 464710.
    • Do not expect to use the 2.57 release yet other than for testing.
    • An unofficial 2.57 is available from WG9's website. We accept filing bugs against it but it is only provided for testing purposes and not very usable at the moment.

Please file bugs only against the browser part or the ChatZilla and debugQA add-ons unless you know a specific problem is new and needs to be fixed. In any case check the existing bug reports to not generate bug noise.

    • If you want to use Rust 1.33 and up you need the patches available on Bills site.
    • See bug 1433370 for current 2.57 breakages.
  • [comm-esr52]:

Release Train

  • SeaMonkey 2.49.5 in comm-esr52.
    • SeaMonkey 2.49.5 will be the next minor release.
      • bug 1512882 tracks the 2.49.5 release.
      • The first manual test builds have been done on the new infrastructure. We still have a problem doing x86 Linux builds on the x64 host. The release is not around the door but shouldn't be delayed much longer.
    • bug 1489785 has been fixed in 2.49.5. Upgrading to macOS 10.14 and up should be ok.
    • The following bugs are not yet fixed in 2.49.5:
      • bug 1409458 "Privacy Issue: Replying to or forwarding an HTML e-mail with external content".
      • bug 1406049 is not yet fixed but has a limited audience.
      • bug 1385667 and bug 1394149 fix build issues with gcc 7. We will evaluate if we can backport them in mozilla-esr52.
    • frg did gcc 7 builds and they had serious redraw problems. We will not use gcc 7 for building 2.49.5 on Linux.
    • clang can be used instead of gcc 7 or 8. Currently these gcc versions produce a non working or "crashy" SeaMonkey.
    • The 2.49.5 release uses the following branches in hg:
    • cZ, DOMi and the Lightning extension might be included using a workaround for the l10n problem tracked in bug 1231349.
    • Official Linux and Windows x64 builds will be done.
    • frg is backporting the ESR60 MAPI fixes for the x64 Windows release.
    • IanN will look into including My and pt-BR locales in a future 2.49.x. frg can create patches based on l10n-release and l10n-central suite but these would need to be manually fixed by the translators and checked into a comm-release branch. We did this with nb-NO in bug 1391174.
    • IanN has patches for missing l10n ready.
    • Because 2.57 is not yet ready we plan to backport security fixes for future 2.49.x releases.
      • frg did backport all but 3 ESR60.2 fixes. He will look into TB 60 Bugs and the prerequisites for the missing fixes later.
      • frg also backported support for VS2017 and the latest Windows toolkit to 2.49. VS2017 will be used for building 2.49.5.
    • frg suggests dropping the 2.49 branch after doing 2.49.5. Updating two branches and also fixing up 2.57 for the next release takes too much time.
      • Plan is to get l10n working for 2.53 and use this for releases after 2.49.5.
      • This will only be possible if we can add enough missing l10n variables to the l10n repos for an interim 2.53 release.
      • 2.49.5 will be the last release supporting Windows XP, Vista and Linux x86.
        • The older Windows versions are no longer supported in Gecko.
        • All major Linux distributions are now 64 bit only and we do not have the resources to support outdated distributions. Linux x64 will stay fully supported.
        • No Linux x86 code will be taken out. So it would still be possible to compile a x86 Linux versions if needed.
        • Because we are using cross compiling we will provide an 2.49.5 x64 macOS build only.
    • Building with the 10.11 SDK need the fixes in bug 1391790 for macOS 10.13.
    • Unofficial Linux builds just need to be declared official.
    • Providing Windows x64 builds is tracked in bug 482143.
  • SeaMonkey 2.57 Gecko 60 in comm-esr60.
    • SeaMonkey 2.57 will be the next major release after 2.49.x becomes EOL.
    • 2.57 will be build from the comm-esr60 repo.
    • Mail and news are still broken in SeaMonkey 2.57 (Thunderbird is now at 60.6.1).
    • Not all patches with l10n-relevant string changes are done for 2.57. frg has figured out a way to do this using strings from later l10n-central releases (suite directory only). He tried this with a local l10n dir and it turned out ok.
      • IanN will test it later but there is currently no alternatives presented.
      • IanN suggested asking Pike or flod about it.
      • With the preliminary solution no jenkins workarounds would be needed.
      • comm-central only patches must not delete any strings in the suite en-US directory until 2.57 is out.
      • When doing patches please make sure to change the l10n labels when the content changes.
      • cZ, DOMi, debugQA and the Lightning extension will be compatible with 2.57.
        • frg should have bug 1231349 fixed soon for 2.53 and 2.57 so the extensions will be included again.
    • Mail and news source structure has been aligned with Thunderbird in bug 1506440.
    • Thunderbird plans to switch to Web Extension dictionaries.
    • We will switch search plugins to a central json file for 2.57. See bug 1300198. TB and Fx did this long ago.
    • frg tries to back out the XUL template removals to make it faster usable again.
    • Compiling 2.57 with rust 1.33 is broken. frg has backported some patches for WG9s SeaMonkey 2.57 Builds.

They can be put in a release branch later if mozilla does not fix this.

    • VS2019 is not able to build SeaMonkey 2.53 or 2.57. The compiler is buggy and currently can not compile some template code.
  • SeaMonkey 2.53 / Gecko 56 in comm-release with unoffical patches.
    • An official 2.53 Beta might be done later.
    • A release would need l10n translations. The temporary solution for 2.57 will not work for this release.
    • A release would need further security fixes. frg tries to keep it as current as possible in his spare time.
      • The big security problems which were in the public up to 60.4 are fixed.
      • The current security level as of today is more or less at 60.3. Goal is to to be on par with latest ESR 60 soon.
      • clang-cl support, ICU60, Skia m66, NSS 3.40.1, NSPR 4.20 and so TLS 1.3 have been backported.
    • The last known regression compared to 2.49.x has been fixed in 2.53.
      • The latest releases work with treeherder. Support for the abort api has been beackported.
    • Bill posts the patch files from frg containing the backported source and fixes on his wg9s website for 2.53.
      • frg maintains the patches for 2.53 on gitlab in a private repo. Anyone who wants access can send him an email but Bills repo is usually up to date.
      • The repo minus any private fixes could be used to create beta branches for 2.53.
    • IanN thinks we can do a 2.53 branch in c-r and m-r so that we can include the backported bugs.
    • frg will do a preliminary 2.53 landing page for the website.
  • General SeaMonkey release issues.
    • ewong tries to fix the update process for the aus3 server. This is broken since 2.48 and did not block the 2.49.4 release.
    • A meta bug for gtk3 compatibility has been created for 2.49.1 and up bug 1367257.
    • When updates are working again the following bugs need to be looked into:
      • bug 1274722 Add %SYSTEM_CAPABILITIES% to the SeaMonkey app.update.url preference.
      • bug 1271761 Add CPU features/detection to update URL.
    • Discussions if we should match minor version numbers with Firefox are still underway. This would need a coordinated change for either c-c or all trees. All minor versions would be changed and the versions would need to be made available in bugzilla. Lightning version calculation needs to be changed. This will be done at a later date and not for 2.49 ESR.
    • Windows x64 releases
    • Unofficial (contributed build) Win64 builds work.
      • Currently tracked by bug 482143.
      • Mapi bug 393302 has been fixed so there is nothing more which would prevent us from releasing a fully functional Windows x64 build.
  • Useful Firefox Release Schedule link: Releases Scheduling
    • Next Merge Day: May 6th/13th, 2019. (moved to May 20th)
    • SeaMonkey is now at version 2.65a1. Gecko is at version 68 and will become mozilla-esr68 later.

Extensions and Plugins Compatibility Tracking

  • Most extensions are now broken in SeaMonkey 2.54+ because of Mozilla api removals.
    • WG9s fixed ChatZilla for 2.57. The patches have been reviewed and checked in.
      • It will probably never work again without a rewrite in 2.58+/61+ because of overlay and other removals.
    • DOMi is broken in 2.56+. See bug 1429936.
      • The developer of DOM Inspector Plus has fixed his extension and we can use the fixes for DOMi.
      • frg has DOMi working for 2.57 using the patches but some minor issues still remain.
        • A work-in-progress version is available at [1].
    • The devtools can inspect chrome content but this needs to be fixed in SeaMonkey. It works in Thunderbird.
      • DOMi might be retired later when this works. It is currently not built. See also bug 1273222.
    • The addon-SDK has been removed.
    • SMILE has been removed in 2.57.
    • Non bootstrapped add-on support has been removed in 2.58+.
    • Bootstrapped add-on support will be removed in Gecko 65.
    • Support for unpacked extensions has been removed.
    • Overlay support has been removed from Gecko 62. Thunderbird did build a lightweight solution for converting existing overlays.
    • Thunderbird has added preliminary WebExtension support to Thunderbird 63.
    • Lightning is packed directly into Thunderbird and SeaMonkey now. This was done in bug 1451847 for SeaMonkey.
      • While packed directly it is still maintained as an extension
    • Add-ons need to switch to optionsType 3 for 2.57. TB did a fix showing the preferences in the menu list. We need to port this bug for 2.57.
  • cZ and DOMi should be integrated into SeaMonkey because of the l10n problem tracked in bug 1231349.
    • IanN suggested forking them and has created bug 1551033. The l10n files for DOMi will be moved into l10n-central.
    • The language pack for cZ will be removed and a translated cZ will be included.
      • frg has this almost finished for 2.53 and up.
  • WebExtension support in SeaMonkey is tracked in bug 1320556. As of now working on this has not started.
    • This would be needed for a ESR60 based SeaMonkey 2.57.
  • Evaluation if some extension functionality should be incorporated will need to be done for the 2.57 release.
    • Lightning is still working in 2.57 and directly distributed starting with 2.57.
    • NoScript, Adblock Plus and uBlock are broken in SeaMonkey 2.54+
    • SeaTab X2 and Version Number work in 2.57.
    • debugQA works in 2.57.
    • Chatzilla 0.9.94 works in 2.53 and 2.57.
  • NoScript Classic 5.x is still being updated. You can get it from [2]. Currently 5.1.9.
  • uBlock Origin is still being updated. You can get it from [3]. You need to pick the latest legacy version. Currently
  • The SeaMonkey and Thunderbird add-ons are now hosted on [4].
    • [5] redirects to it. 2.57 has already been switched over to the new site in bug 1475799.
      • 2.57, comm-central and the inofficial 2.53 already have updated prefs. We plan to do this for a future 2.49 release.
    • The old add-ons website api has been removed in bug 1402064 for Gecko 60 and up. We might need to do some further porting here to smoothly

integrate installation from the add-ons site.

    • For Thunderbird a new add-on [6] is available to switch to addons.thunderbird net.
    • The website has been updated and points to [7].
  • We will evalute the possibility of shipping pdf.js with SeaMonkey in a future release. frg will look into it when he finds some time.
  • Mozilla removed all classic add-ons from AMO. Rainer_Bielefeld filed bug 1517828 to see if missing add-ons can be re-added. The add-on converter also no longer works because of this.
    • Suggestion is to use a third party archive ca-archive and xpi.

2.x (Last, Current, Next)

  • See Basics page for the usual reminders.
  • Old add-on signing methods have been removed. SeaMonkey and Thunderbird still use them per thread "removing "the old way" of signing add-ons" in Apparently xpinstallConfirm.xul contained the references to them.

2.49.x current releases

open tracking (0) tracking requests (1) targeted (0) fixed (83)

2.57.x next release branch

open tracking (0) tracking requests (2) targeted (0) fixed (110)


  • Sync is no longer working. The goal for 2.53 and 2.57 is to restore sync 1.1 and set up a sync 1.1 server.
    • Sync 1.1 has been removed from the mozilla source tree. If we want Sync 1.1 to work we need to fork it.
      • Pro: We control our own sync server and are not left at the mercies of Mozilla the next time they change their sync system.
      • Pro: Our users don't need an Fx Account.
      • Con: Can't sync with Firefox (unless someone writes a Sync 1.1 client for Firefox).
    • The sync ui has been disabled in 2.57+ in bug 1432273.
    • Long term we need someone to work on porting sync 1.5 over to replace legacy sync code after 2.57.

See: New Firefox Sync has landed in Firefox Nightly. Tracked in:

      • bug 998807 Sync account creation or device pairing fails with exception in BrowserIDManager.
      • bug 1003434 Add support for about:sync-progress.
  • frg suggests doing an about:credits page for SeaMonkey contributors. This should link to a new list of people on the SeaMonkey project page.
    • IanN suggests about:smcredits.
    • The mozilla credits page still must be linked because there are many SeaMonkey contributors in it and Gecko is also still the foundation we did and are building on.
  • Tests are broken. Priority for new features or ports according to IanN is to get the code working.

frg suggests splitting off the tests to separate bugs for tracking and hopefully fixing in the future. With the current dev resources at hand he is not very hopeful about fixing the tests anytime soon.

  • Stalled. Needs a kick:
    • bug 815954 Click-to-Play: Port bug 812562 (click-to-play blocklisted plugins: reshow urlbar notification as with normal click-to-play).
    • bug 476108 GetShortPathNameW fails under some NTFS junctions [patchlove].
  • Current breakages:
  • Mozilla-central bugs that affect us:
    • A lot of these bugs are due to mozilla-central switching from synchronous APIs to Asynchronous APIs.
  • [rsx11m] did open bug bug 1305902 for certificate pinning. Discussion if it should be enabled for SeaMonkey is still underway. Callek commented in the bug.

Feature List, Planning

Bug statistics for the last two (full) weeks: — 8 new, — 8 fixed, — 2 triaged.

  • generally low activity on trunk, focus on branches towards releases

Open reviews/flags: 14 review 3 super-review 1 ui-review 9 feedback

  • See Feature List page for major wanted/needed features.
  • TODO:
    • Encrypted Media Extensions / Digital Rights Management
      • bug 1127784 added a preference and UI to enable/disable playback of Encrypted Media Extensions, with UI seen in non-release builds only
      • More work appears to be needed to download necessary 3rd-party Content Decryption Modules, some UI can probably be ported from Firefox
  • Fundamental core features Firefox/Mozilla plans or did remove:
    • bug 1446341 The XUL "tree" widget will be removed from mozilla-central
      • Major bummer, will affect MailNews and other windows, Core bug 1446335
    • bug 1444685 XUL overlays are gone (SeaMonkey)
    • bug 1222546 Product plan: remove support for heavyweight themes
      • This has been officially removed with Firefox 57. With Firefox 61 theme support has been removed from the source. The Modern theme no longer works in SeaMonkey.
    • bug 1397874 tracks the xbl bindings removal. Only bindings used in Firefox will be kept for now until they are replaced with who-knows-what.
      • Overlays are now also gradually being removed. Mozilla has converted tabbrowser.xml to tabbrowser.js. Needs to be done for SeaMonkey in a later release too.
  • The website and wiki are outdated. InvisibleSmiley no longer maintains the website. The website was updated but it still needs work. Volunteers welcome.
  • frg suggested asking for donations in a future release. Probably during startup or more prominently on the website.
  • frg suggested a tabbrowser.xml overhaul because it's becoming harder to backport fixes from Firefox.
    • IanN suggests doing small patches which are easier to review.
  • There are reports that the PayPal donation on the website doesn't work for USD. It seems the amount is converted to Euro (probably correct if it is a German account).
  • Images should be vectorized and be svg if possible for future updates and HiDPI compatibility.
  • bug 1414390 needs to be ported. intl.locale.requested locale list needs to replace general.useragent.locale. Thunderbird did this in bug 1423532.
  • More and more websites do poor browser sniffing or pretend to require a later browser version.
    • We need to evaluate if a user agent switcher should be incorporated into SeaMonkey.
    • For some google servicves like maps you need to set a plain Firefox useragent to avoid problems.
    • For github you need to set the gecko Version to 60.
    • We plan to add a generic user agent for github and 2.49 / 2.53 only. See bug 1505460.
  • bug 1463738 Bookmarks descriptions are taken out of Gecko 62.
  • Live bookmarks and rss support is taken out of Gecko 63 in bug 1477667. bug 1477670 might affect us too.

Roundtable - Personal Status Updates

  • IanN generally will handle more complex review requests. frg, rsx11m, stefanh and ewong can also do reviews in their areas of expertise. For bigger changes and branch approvals outside of the build system IanN needs to be involved.
  • a+ from trusted regular patch authors/reviewers for ESR60 / 2.57 is implied as long as it only affects the suite directory. This will change back to a general needed a+ when the tree becomes more stable and will be announced then. If in doubt ask for approval.

Status Updates from developers - what are you working on, what's the progress, any other comments? (feel free to add yourself to the list if your name is missing and you have interesting status).



Most work for SeaMonkey in the last two weeks was below the waterline but together with IanN and ewong we set up the infra for local building so that we can deliver 2.49.5 and friends finally.

Waiting for review:

  • bug 1274798 Seamonkey integration in Gnome3. Old bug/patch which needs verification from someone more familiar with Linux.

Waiting for esr60 a+:

  • Nothing

Waiting for feedback:

  • bug 1410646 Fix SM "log into/onto" and related instances.

Checkin ready:

  • Nothing


  • bug 1536779 Port |Bug 1528840 - addressingWidgetOverlay.js, abMailListDialog.js code cleanup| to SeaMonkey.

Working on:

  • bug 1231349 l10n repacks broken on with SM 2.42 and newer. cZ patch done for 2.57 and up. Got feedback but found a bug yesterday. Backport to 2.53 later.
  • bug 1231349 l10n repacks broken on with SM 2.42 and newer. DOMi patch mostly working. cZ got f+. Shooting for r+ next.
  • Doing local 2.53 l10n builds to assess how much would be missing for a possible release.
  • Fixing up mailnews for 2.57. Starting to see if I can back out the xul templates removal to speed things up. Second bug backed out but still no luck.
  • Backporting ESR 60 fixes to 2.53. At 60.3 now.

  • bug 1392929 Port Bug 886907 [Remove old synchronous contentPrefService] to SeaMonkey.
  • Followups for bug 1379369 to TriggeringPrincipals and UserContextIDs in more functions.
  • bug 1370314 SeaMonkey 06/2017 installer rollup. Probably not much more right now. Took some parts to other bugs. and will see what is left when 2.57 is ready.
  • Helping MMR with bug 1444740 Drop support for -moz-border-*-colors in SeaMonkey. He seems to have dropped out :(

Mostly shelved for now because no time:

  • bug 1374094 Update debugQA extension for older SeaMonkey versions. Need to move a function from editor into the patch and retest it.
  • bug 1402645 Build Lightning binary components for 2.49.1. Needed for 2.49.1!. Temporary fix in the esr branch. With l10n working probably best to just close it wontfix.
  • Putting updated debugQA and DOMi extensions on TBN. Started with debugQA and noticed that it was no longer compatible with older versions.


  • Mostly did infrastructure, backporting, doing reviews and support work in the last two weeks.

Looking into:

  • bug 1441016 Port bug 1414390 "Add intl.locale.requested locale list to replace general.useragent.locale" to SeaMonkey

Not really working on:

  • bug 1437393 Font lists in preferences are no longer grouped by font type, port asynchronous handling like bug 1399206
  • bug 1318852 Make labels of cmd_properties action-oriented and context-sensitive, e.g. "Edit Contact", "Edit List", etc.
    • "real" fix



Any other business?

  • The next meeting will be held in two weeks on Sunday May 26, 2019, 14:00 UTC (16:00 CET).
