    I have the dark theme disabled in Thunderbird but I still have dark backgrounds with white text happening on all my outgoing messages. Driving me nuts!

      Mostly a dark theme issue.

    The Latest Mozilla update is absolutely full of bugs. It is obvious that no one designing any element of any application from them actually TEST their code. Version 91.5.1 from Mozilla TB has an ‘improved dark mode theme’, however someone coded a FORCE dark mode in the actual code. This can be easily identified by selecting any theme that isn’t dark mode, and you get some elements in the theme and rest in a mix between light and dark with the majority being a poorly implemented dark mode that is nothing more then preforming a color inverse on everything including text.

      Yes seems to be like a beta or testing software.

    Problem still in version 91.10.0
    So probably nobody cares about that issue.
    Does anybody know where to report this?

    TB looks just ugly and is not usable.
