Thunderbird 115.0 issues

tl;dr: No major issues found in SUMO. As expected, unsupported customizations from 102 broke in 115 and the new user interface in particular the Unified Toolbar led to a few issues for some. Carryover issues from 102 and earlier releases.such as MS OAuth, Exchange, etc continued.

• Awesome Thunderbird support volunteers and staff: Please add any issues to this page using the tagging convention from Wayne and Roland: tb115, bugx, etc.
• This page is a curated summary of: Thunderbird/Support/TB115.0SupportIssues/Details

Not so minor

(not in order)

• 1843637 v115 fails to subscribe Imap subfolders at folder hierarchy-depth > 2; v <=102 works OK filed July 14, 2023 <-- I don't think this was discovered in SUMO. <-- UPDATE 31July2023: We believe this is fixed in: bug 1843637: "v115 fails to subscribe Imap subfolders at folder hierarchy-depth > 2; v <=102 works OK". This fix will be part of 115.1 which will be out the week of August 7th if things go as planned.

Minor issues

(not in order)

• Middle click does nothing tb115, in 102 it opened a message tab in the background. There is as possibility the fix for this will be backported to 115. See

bug 1842482 'Reimplement middle click "open message in a tab" action'

• Unified Folders
  • 183672: unified folders doesn't show spam folder <-- WORKAROUND: "If you right-click on the unified folder and click on Properties, you can choose the folders that the unified folder looks in."
• add your issue here :-)
• Printing
  • 1843628: Printing issues with HTML E-Mail (only email headers and big whitespace on first page) <-- " just sending a simple (HTML) mail with two lines of text from Outlook and trying to print the received mail in Thunderbird results in this behaviour. (Setting to simplified HTML circumvents the issue, but that page is then no longer correctly formatted of course)."
    • Multiple instances: 1418762: Printing Issue with latest update ; 1418770: Thunderbird Email and Printing; 1419283 from July 25
    • Canned Response:

There is an (untested by me since I can't reproduce the problem) workaround (some subtle HTML formatting might be lost): 
# On Linux and Windows, hit the alt key to display the menu (not needed on Mac)
# View > Message Body As > Simple HTML
# Print the email

• people wondering why the hamburger doesn't have every option
  • 1418307 Run Filter on Folder not in App Menu
  • 1418335 Thunderbird 115 (Linux) Clear Recent History not available in Three-bar aka App Menu >Tools menu, only Menubar>Tools
• people wondering how to add the menu bar
  • 1418183 So I want my UI to look proper so title bar at the top, with the title only, menu bar below it, and the rest tabs etc below that, you know like i trained my brain for the last quatre century.
• people wanting to get rid of the Unified Toolbar
  • 1418557 I tried "Customize..." but looks like it doesn't allow to customize anymore, toolbar buttons editing only., same issue: 1418375 How do I remove "Unified Toolbar" in Thunderbird 115
  • 1418113 How to remove the new toolbar in version 115? <-- jschroed57 has an unsupported userChrome hack :-) in this question
• A few people complained they can’t zebra stripe the Message List Pane like they did in 102 (which was not the default so they must have used an add-on in 102 or are using 9x or 7x?!?)
  • 1418513 mailbox display with alternating lines of white/grey backgrounds in Thunderbird 115? <--- T-H has a userChrome hack :-) for this
  • 1418491 Grid lines (or "zebra striping") in Message list view? <--- David has a userChrome hack :-) for this
• customizations (please note that userChrome.* has never been and will never be supported):
• * 1419774: Change Folders to be red if it has new mail
  • 1418612 Want to change the background colour of Message List Pane on macOS Ventura, too much contrast in Dark Mode
  • 1418148 Move Tabs to Unified Toolbar to reclaim vertical space
  • 1419564: Folder Pane: Change fontsize & remove bold
  • userChrome.css worked in 102 broken in 115: 1418599:I want the unread messages in the list of messages pane to be "orange"
  • userChrome.css worked in 102 broken in 115: 1418292 It appears only part of my userchrome file affects customization in latest release (115)
  • userChrome.css worked in 102 broken in 115: 1418273 Thunderbird 115 now ignores my userChrome.css for Message List Pane
  • userChrome.css worked in 102 broken in 115: 1418271 supernova unified toolbar button colors
  • unsupported userChrome customization recommended by contributor: 1418269 Would like Menu Bar above the Unified Toolbar, same issue: 1418243, 1418219
  • 1418356 Message list Pane display font not customizable & missing "get mail" button <-- get mail button is there in 115, not sure why this person doesn't see it

MS OAuth & Exchange related issues (relevant tags: msoauth, exchange):'

• Changing from OAuth to "normal password" allows people to send emails: 1419635
• Another theory about some hotmail/outlook.com/live.com email issues is that people are entering their password into the "Set Up Your Existing Email Address" which causes it to fail. Instead folks should leave the password field blank and click Done which will cause their browser to open up and ask for the outh password. Instances of this issue: July 29, 2023: 1419686
• 1419572: is a typical example of not being able send email <- Could wrong SMTP server in a multiple account situation (where 1 or more accounts are hotmail or outlook.com or Microsoft/Office365 accounts?) be the cause of many people's issues?

Antivirus

• Often AV software breaks new versions of Thunderbird until the an update is released. Don't use AV from anybody except Microsoft if you are on Windows is my informal recommendation since all 3rd party AV are worse than MS's and break TB for longer in my anecdotal :-) experience
• July 29, 2023 1419642: On latest update of TB, all my settings have again been scrambled (it takes forever to go though every setting on TB!) and I've again lost the BD spam toolbar, even though it is installed and enabled. ...Uninstallation of Bitdefender using the Uninstall Tool downloaded from the website, rather than Uninstall in Windows , followed by a scan with the programme Everything and removal of another 5 BD files finally removed the BD extension from the Manage Extensions list! <-- I wish I could say that BitDefender or any antivirus software has a great track record of updating consistently and not breaking TB randomly. But no AV vendors are consistently bad that way :-) There is a new version of Bit Defender, 27.0.86, released on July 31, 2023. Perhaps it helps?
• mozillaZine: 3111707: Avast blocking sending mail for outlook user <-- found July 29, 2023 workaround: uninstall Avast One (disabling it didn't work)

Add-ons

The following is an incomplete list of add-ons that have issues in Thunderbird 115. Please add to this list add-ons that have issues and if you find an add-on has been updated and works with Thunderbird, please strike it out using <del></del> (not in order,numbered for convenience)

• July 27, 2023: protz's Manually Sort Folders is broken in 115 (see msf issue #199), luckily there's a beta version (which has issues with sub folders and unread counts but otherwise works): Manually-Sort-Folders-v3.2.zip <-- beta 3.2; SUMO Questions: 1419526: In pre 115 versions I used the "Manually sort folders" add-on to sort folders to how I want to prioritise them
• Import Export Tools NG (IETNG) is broken in 102. But happily v14 beta 6 of IETNG works :-) see: https://github.com/thundernest/import-export-tools-ng/issues/408 ; SUMO Questions: upgraded to ver 115.0.1 & now can't get importexporttool to work!!! can't use it without this tool
• August 4, 2023 : 1420174: "Outlook Address Book Enabler" causes Thunderbird to take 60 seconds to start i.e. slow start! <-- "Outlook Address Book Enabler" version 1.0.2 last updated May 19, 2023. Hopefully fixed in future versions.
