Isn't this a bug in Firefox? In chrome with the same theme this doesn't happen. Shouldn't I report this to Firefox bugzilla instead?

Comment 3 Nate Graham 2019-08-06 16:49:54 UTC

It was a Breeze theme bug actually. Fixed with the fix for Bug 356006 though!

Comment 4 Nate Graham 2019-08-06 16:52:23 UTC

Actually never mind, my mistake. Not fixed yet.

Comment 5 Nate Graham 2019-08-06 16:58:56 UTC

As of Plasma 5.17, this is not a problem when using Breeze Dark or Breeze Light. Just default Breeze.

Comment 6 Nate Graham 2019-08-06 17:54:02 UTC

There's a first-attempt patch to fix this: https://phabricator.kde.org/D22452

...but I don't think I am going to continue working on that patch, this problem is beyond my abilities.

Comment 8 Nate Graham 2019-08-10 22:40:21 UTC

This is mostly an upstream bug in Firefox itself (https://bugzilla.mozilla.org/show_bug.cgi?id=1562507) but we can try our best to work around it.

I did, sorry about that.

Comment 14 Patrick Silva 2020-01-29 03:38:35 UTC

Still happening on Plasma 5.18 beta + Firefox 72.0.2.

Operating System: Arch Linux 
KDE Plasma Version: 5.17.90
KDE Frameworks Version: 5.66.0
Qt Version: 5.14.1

Comment 15 Patrick Silva 2020-06-14 12:51:19 UTC

Same thing on Plasma 5.19 + Firefox 77.0.1.

Comment 16 Patrick Silva 2021-05-14 16:00:26 UTC

Still an issue with Firefox 88.0.1 and Plasma 5.22 beta on Arch Linux.

Set global theme to Breeze
Set color scheme to Breeze
Use default theme of Firefox

Comment 17 Podagric 2021-06-03 13:26:42 UTC

With the new firefox proton UI, this got even more annoying

Comment 18 Nate Graham 2022-05-09 21:28:39 UTC

Firefox has its own tab styling now and doesn't respect the system theme anymore. :( So I guess this isn't a problem anymore from breeze-gtk's perspective.
