In Firefox 130, if you have high contrast turned on in Win10 (and possibly you have to be using the dark theme in Firefox), white outlines appeared around all buttons in the interface. It's not a major thing, but it's a real nuisance as it ruins the appearance of the dark interface and, much more importantly, if you tend to work in dark rooms, it adds a lot of white to the screen, which can cause glare and eye strain.
It would be great if the devs could remove the white outline in the next update.
