Firefox on Debian 13 with XFCE: Firefox doesn't respect my GTK theme, except if the theme's name ends with "-dark"

Hello,

I just set up a computer with Debian 13 'Trixie', and I downloaded and installed the latest Firefox for Linux (version 145) from Mozilla's site.

Then I noticed at first that it wasn't following my GTK theme. Then after testing a bit, I discovered it would respect only themes with names that end in "-dark". I've taken some screenshots and attached them to demonstrate the problem.

firefox-esr from Debian's repositories didn't have this problem. But also, I've got another computer that still has an older distro (Debian 11) installed, and I'm running the latest firefox 145 on that too, and it always respects my GTK theme regardless of whether its name ends in "-dark". So, perhaps this is a GTK/GTK4 problem or something?

Does anyone know about this issue, can anyone help? I would really like Firefox to respect my choice of theme regardless of whether the theme's name ends with "-dark" or not.

Hi there,

Thank you very much for bringing that up! Could you please file a report on Bugzilla, Mozilla's bug tracker, so that the developers can take a look?

If you create a report, I'd appreciate you posting a link to it here. If you don't feel comfortable enough with that, just let me know, and I'll file a bug for you.

Hi Denys,

Thank you, a lot for your reply, and offering to help, I appreciate it. I have reported it now: https://bugzilla.mozilla.org/show_bug.cgi?id=2003099

Sorry my report is a bit long and wordy, I wasn't sure how to best write it.

I really appreciate you and anyone looking into this issue.
