(Firefox 130.0, System theme — Windows 11, high contrast yellow on black theme.)
With the new update (130.0), on its toolbars white boxes appeared around each icon on the black background of the toolbars, and my Firefox now looks like the Times Square at night.
To get an idea of what I mean, compare Firefox:

with Thunderbird:

How can I remove the white boxes from the toolbars?
