Thunderbird 3 Beta 4 Schedule

August 19th, 2009 Posted in Mozilla, Thunderbird

We’ve now agreed the freeze schedule for Thunderbird 3 Beta 4:

  • Slushy Code Freeze: Monday 7th Sept 23:59 PDT.
  • Full String Freeze: Wed 9th Sept 23:59 PDT.
  • Code Freeze: Friday 11th Sept 23:59 PDT.
  • l10n-mozilla-1.9.1 Freeze date: Monday 14th Sept 23:59 PDT.

We’ve got a lot to do before the release and before the final release. Here are just a few ways you can help us get there faster and help make Thunderbird 3 even better:


We’ve still got a lot of blockers in the list, some of them are currently un-owned (assignee is If you wish to write a patch for a bug please do so, if you haven’t got privileges to assign the bug to yourself, please comment on the bug so we know you’re working on it. If you stop working on the bug, please reassign to the default owner so that we and others know.


If you can, help out with bug triage, writing test cases and test days. See the QA page for more information.


We want to improve our documentation – especially for extension developers (but for ourselves as well), see Jen’s blog for how to help.

    I just downloaded and installed the Thunderbird 3 beta for the first time… not sure if I like the new theme.

    The ‘new items’ icon is barely visible over the feeds icon (which is um, very big and bright), and the folder icon is a little too bright yellow for my eyes’ liking, too.

    Yeah, I liked the old icons better. They were more subtle, less square, and had more spacing around them. Well, I guess (hope) there’ll be a theme available on AMO with the old icons, but it would be nice if the default theme could be improved a little.
