User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:141.0) Gecko/20100101 Firefox/141.0

Steps to reproduce:

update from FF 140.x to FF 141.0 on Linux Mint with dark mode system settings and FF configured to use system settings.

Actual results:

FF 141 ignores system settings and displays GUI in light mode. Switching to dark mode still leaves bookmarks sidebar in light mode.

Expected results:

Display GUI in mode defined by system, i.e. dark mode, as it was before the update.

See bug 1978639 where I investigated this. I suspect it's the same issue.
