6.13.1 - Published 17/10/2025

Maintenance Release 6.13.1

• Made compatible with Thunderbird 145.*

  There is a bug on thunderbird.net that may not be propagated to some users when we increase max version compatibility; this can lead to a false report of the Add-on appearing as incompatible with the current version.

  I raised a bug with Thunderbird to address this problem: [Bugzilla 1986027]. Please vote with us for getting this fixed!

• Added Norwegian locale [issue #617].

Improvements 6.13

• Made compatible with Thunderbird 143
• Fixed missing/broken menu icons in all popup menus of Thunderbird 143 [issue #602]
• Minimized impact of "News Flag" — now displayed as a badge icon 🟠 [issue #607]
• Intermittently, current folder bar was not displayed on main 3pane (first) tab [issue #608]
• Toolbar button icons sometimes don’t update immediately when changing themes [issue #611]

Bug Fixes

• Fixed: QuickFolders toolbar was not displayed on startup in Thunderbird 143, with toggle button not working [issue #609]
• Folder navigation buttons can now be removed independently of Message Navigation buttons - they were falsely linked to the message navigation settings [issue #610]

Unconfirmed

• quickMove with history should move mail but jumps to folder instead [issue #606] I have seen this rare behavior intermittently and am currently investigating how to fully replicate it
