For the last couple of days, the Firefox instance goes black and the title bar turns to an old windows look (see picture). Or turns fully blue, the color of browser theme, and the title bar is covered as well. There is no certain page that makes this bug appear, it appears randomly regardless of the page I'm visiting. Often it happens on the Firefox instance that is on the monitor I'm not working on at that moment. For example, I am browsing on my main monitor, and the 2nd monitor has a page open, the page in the 2nd monitor becomes bugged. It happens the other way too. Current Firefox version is 149.0 64 bit version, but i think it happened before the update too. I have already tried to turn hardware acceleration on and off again.

That sounds like a GPU/rendering issue, especially since it’s happening across monitors. Even if you already toggled hardware acceleration, it might be worth updating (or rolling back) your graphics drivers — sometimes newer versions actually introduce glitches like this.

You could also try running Firefox in Troubleshoot Mode to see if any extensions are causing conflicts, or check if it happens with a fresh profile. Multi-monitor setups can sometimes trigger weird behavior too.

I’ve seen similar display quirks even on platforms like phonexa when GPU acceleration or rendering isn’t behaving properly, so it’s often tied more to the system/graphics side than the app itself.
