89.0 64 bit not honouring theme colours

more options

Windows 10 Pro, 20H2 (19042.985): Updated to FF 89.0 and found that the color disappeared off my browser Menu and Tab toolbars. I have tried using Windows default AND custom theme colors (using FF Colors). it stays white (or colorless). When I go back to 88.0, it works correctly. Is this a know bug and/or should I be reporting it somewhere?

Cheers 'n thanks

PS: I sync across PCs. On any of my PCs, updating to 89.0 encountered the same error, so it is not PC specific

The new "System" theme doesn't seem to pick up a new background color from the system. I don't know what was intended. If it's a bug, I'm sure a bunch of people have filed it by now, but you could check on

Meanwhile, if you prefer the colors of the "Default" theme from Firefox 57-88, someone created an add-on theme that emulates it. You can give it a try here:
