Steps to reproduce:

107.0b4 (64-bit), Windows 11
Have applied the default dark theme to TB

Actual results:

The colour contrast between active and inactive tabs doesn't help with visually identifying them.

Expected results:

The active tab should standout a bit more visually, compared the inactive ones. Earlier there was a thin blue band above the active tab.

Earlier there was a thin blue band above the active tab.

I'm using Oct 26 build on Mac. The shading difference is too subtle IMO. It does have the blue band, so no band is a regression.

I'm on Windows 11 too and I see the blue line with the TB dark theme. Also in maximized mode.

I'm on Windows 11 too and I see the blue line with the TB dark theme. Also in maximized mode.

Went back and checked - I actually have "System theme — auto" as the theme. Since my Windows11 theme is the dark theme, TB applies the dark theme too. In this case, as per my initial report, the blue line is not visible on the active tab.

I notice that if I apply the dark theme explicitly, then the blue line appears on top of the active tab.
Would be nice if the "System theme — auto" provided a blue line highlight for the active tab too.

My apologies for the confusion in the initial report.
