Blocker Report

Firefox 3.6 RC Code Completion

All Blockers (includes website, release management, etc)
See more Firefox 3.6 related blocker queries, or learn about the new status and blocker flags

Browser / Front End

  • no blockers
  • you're going to see some UI churn on trunk, get used to it
    • This will cause change. Things will not be the same as before.
    • IF YOU SEE A CHANGE YOU DON'T LIKE: Please sit with it for at least 48 hours before blogging/tweeting/irc pinging to tell us how terrible it is.
    • Change is hard, but important. We value input more than insults.
  • this quarter our big targets are:
    • starting UI changes for Firefox 4
    • reducing I/O on the main thread (performance)
    • supporting out of process plugins work (UI and integration work)
    • continuing to drive startup time
    • integrating jetpack, weave and iterating on personas

GFX Update

  • No blockers
  • Some interesting things we're working on:
    • Hardware Layers implementations (DX10 and OGL) (Bas)
    • CoreAnimation plugin support (Ben Girard, our new co-op!)

Layout Update

  • No blockers
  • Things quiet due to holiday
  • Basic layers infrastructure coming up [roc, bas]
  • DPI rework [roc]
  • CSS calc() [dbaron]

Content Update

  • no 1.9.2 blockers
  • slow going due to holidays...
  • investigating one regression in plugin code bug 536020.
  • benjamn writing xpcshell unit tests for CPOWs (f.k.a. JPWs).
  • Jonas is changing nsIAtom (API compat)

Platform-specific Support Update


  • finishing last few blockers
  • ramping up work for future releases, more on this next week
  • landed Object.definePropert{y,ies}, Object.create in TM repository
  • just before last platform meeting landed a change to align behavior of setting properties with getters but not setters with ES5; blogged to anticipate any potential bustage out there

Startup Performance


  • Zack landed a patch for Cross-domain data theft using CSS parser, an issue that affected all browsers because it is almost a hole in specs. But it breaks some web sites; do we want a more conservative (but more complicated) fix for branch?
    • We had a long discussion about this.
  • Please complete the triage of crash bugs in your component. Over the second half of 2009, the number of open crash bugs was reduced by 25%, largely through the security team's aggressive GTD-style triage (which also identified at least three security bugs among the heap). The remaining bugs should have a high usefulness density.
