Does Firefox still break Windows turning monitors off or have they finally fixed that? Vivaldi is having some performance hitches and if they finally made Firefox not burn a hole in my OLED monitor I'd re-examine using it

I leave Firefox open all the time and Windows happily turns monitors off as instructed. Never run across the issue you’re referencing.

It's not a very common issue but it's been an issue for years, this is just one of the bug reports filed on this: bugzilla.mozilla.org/show_bug.cgi... I've had this problem going all the way back to the Win10 days, it's one of the big reasons why I don't use Firefox
