I had the Firefox menubar/tabs set to be the same as my Win 10 system's theme color (Settings > Personalization > Colors), the same as the color of the taskbar. When Firefox v. 92.0 self-installed on Sept 7, 2020, the menubar/tabs color reverted to Firefox's default, a dull gray.
System Theme in Add-ons Manager > Themes is still enabled.
How do I get Firefox to partake of the Windows system theme again?
This has happened before when Firefox updated, although it doesn't happen EVERY time. The last time it happened, I recall being able to find a simple about:config adjustment on Google (not on this site), but I can't find it now. (As I recall, it was an about:config item that didn't sound like it would affect the menubar color, but it did.)
I have another laptop on which I rushed to disable automatic updates, so Firefox on that laptop still shows the system color. Is there a file in the Profiles folder I could copy into the problem computer that would restore the theme color setting?
