Tab group: Color the whole tab instead of just a thin highlight line

[Domiragi]

Hi, I need some help with configuring. I was reading through the wiki, and in the section for Tab Group Options, the example videos show that tabs in the tab group have their whole tabs colored instead of just a thin highlight line as with base Firefox:

I 've read through available options in about:config, but I can't find what I need to set to enable this. Can someone point me to what I need to change to achieve this? Thank you.

Hi, thanks for taking the time to reply. So I decided to test around, and I found out this issue was happening with the current source version, but it works fine with the release version 1.9.8.5. I found the setting, ultima.xstyle.tabgroups.with.colormix and setting this to true with the release version makes the whole tab colored as expected.
At first I thought the issue with the source version was that the source version has the folder utils with files for autoconfig, and that I had MrOtherGuy autoconfig on my machine already so I thought it was causing something weird, but after removing the utils folder and restarting, the issue with the source version still persisted and the tab only had the highlighted line:

So I think the issue may be in the changes in the CSS files between the release and source version.
Also, I found some other weird issues with the current source version, maybe it is intended or maybe you're already aware of this, but I just want to note here just in case. I'm running this with Firefox version 136 on Windows 10. If you think these are bugs, I can open an issue ticket for it:

• Context menu's and main menu's backgrounds are transparent:

• Searchbox icon appears in the searchbox and doesn't disappear when there is text:

I got the original issue solved, so I'm gonna mark this question as resolved. Thank you for your work on this project!
