  • Version 3.3.17

    Released Dec 17, 2025 - 9.65 MB
    Works with firefox 109.0a1 and later
    NEW FEATURE:
    - Automatically widen the conversation to avoid horizontal scrolling on HTML emails that are wider than the desired message max-width. For now, this is on for everyone with no way to disable it – I’m hoping this doesn’t need to be a preference.

    IMPROVEMENTS
    - Prevent the new chat side bar message bubbles from being full-screen (a side effect of Simplify making chat quick search full-screen)
    - Switch themes via quick settings instead of the full themes modal (should be faster and may be more reliable)

    - New option to hide "Share in chat" button and minimize that and the reaction button instead of fully hiding it

    IMPROVEMENTS
    - Check if closed bundle location needs to be updated when refreshing the list due to removing the first thread(s) in the bundle earlier
    - Improvements to always showing the from/to fields (max height and hide the cc/bcc option if main toggle for from/to fields is off)
    - Rename Flows as Workspace Studio and use double quotes in all Simplify prefs

    FIXES
    - Fix recent regression around creating and editing autoCopy (cc/bcc) rules
