Not sure what the problem is, gtk apps refuse to use correct theme and font settings on wayland. As far as I know, it can be worked around by installing gtk xdg desktop portal.

I had switched my global theme to Breeze Dark. Nevertheless Firefox used a light theme when I launched it for the first time. Interestingly, at further runs Firefox properly came up with a dark theme. But I had restarted my session in between and also had removed and reinstalled the Firefox snap, so it's possible that one of these actions triggered Firefox to finally use a dark theme. 2. The font size in the UI is too big (compare with other KDE apps on screenshots). 3. It apparently doesn't use Breeze (light or dark) as the UI theme, but something else (Adwaita I guess). 4. The mouse cursor uses the wrong theme and is too big (it changes visible if move the cursor in and out of the Firefox window). 5. If I click e.g. on "File -> Open file...", the file dialog is not the one from KDE but the one from GTK/Gnome. And the UI text is displayed in a rather jagged/distorted way (see screenshot). The issues described above do _not_ appear: * If I run Firefox as snap in Plasma X11 session. * If I run Firefox as deb (both Plasma Wayland and X11 session work fine).
