1704086 - Proton Tab Strip has wrong background color when browser.tabs.drawInTitlebar is false

Status: NEW

(Firefox :: Theme, defect, P3)

Description

[Mathieu Pillard [:mat]]

Attachment: tabstrip.png

STR:

• Use default theme
• From Customize Toolbar menu, check "Title Bar" to keep the regular Operating System title bar (that sets browser.tabs.drawInTitlebar to false)
• Open a few tabs

Expected Results:

• Tab strip is has a different color than the active tab, making the active tab easy to distinguish

Actual results:

• Tab strip is the same color as the active tab (it's hard to distinguish between the active tab and the inactive ones)

Note: Not reproducible when "Title Bar" is unchecked - in that case the tab strip background is darker than the active tab as expected.

For comparison : what it looks like when the Title Bar pref is flipped back to the default value. The tab strip background is different and we can distinguish the active tab from the others much more easily.

For the record, this is with Ubuntu Linux 20.04 LTS (Adwaita GTK theme) and the Firefox "Default" theme, which follows operating system color scheme.

I've the same problem using XFCE with the default theme: there isn't enough contrast to easily distinguish to focused tab.
