Firefox tab bar color does not follow theme

[zhenhua-wang]

Thank you for this wonderful theme!

I find this issue with firefox (fresh install) that its tab bar color does not follow theme. As you can see from the image below, only buttons are correctly displayed, not the tab bar itself. I tested this with Gnome 46 and MATE, both DEs have this issue...

Since chrome (and all other apps I use) works very well (check the image below), I suspect that this issue might be related with theme.

I tried with other themes and it appears that Firefox doesn't apply decorations to its headerbar.

You have two options, AFAIK:

1. Use a Firefox theme, like this one
2. Right-click the titlebar, select Customize Toolbar and check the Title Bar checkbox:
   

I'm sorry not being able to help more. I'll leave the issue open in case someone else finds a solution I'm not aware of.

Thanks for the quick response! I tried both options. Option 2 is a good temporary fix for me. Option 1 unfortunately will have gnome-like button. Thanks again for all your efforts!

This is now impossible as:

1. Firefox prior to 139 removed the ability to use image textures on a 'disabled titlebar' tabs toolbar, forcing solid colours
2. Firefox 140 (ESR) has completely deleted any and all GTK styling from Firefox (only colour palettes remain)
