Created attachment 868382 [details] Firefox 102 Hello, I am running openSUSE Leap 15.5 with KDE Plasma desktop environment. After installing patch with MozillaFirefox-115.0-150200.152.93.1.x86_64, my Firefox appearance has changed. All fonts in the Firefox are 150% of desktop environment fonts. Attached here are screenshots to demonstrate the issue: 1. Firefox appearance before the update (102) 2. Firefox appearance after the update (115)

Hm, others using KDE can't reproduce this issue. So it seems to not be a general problem. Could you try the following modifications to your env, so that we can narrow down, where this might be coming from: 1. Try with a new Firefox profile and see if the error is still there 2. Try switching between X and wayland 3. Try a different desktop env Thanks!
I've found that the reason for the issue is forceFontDPI=144 in my ~/.config/kcmfonts However, this option is enabled by my intentionally, and the Firefox had been working well for a long time. Now I suppose that Firefox accounts for DPI scale twice.
96+48=144, which is halfway to 192, (96*2), a breakpoint between two extremes. If 144 was helpful in the past, you might wish to try 143 instead of removing it.
I've tried 143 and nothing changed (at least visually)
Recreating new profile helps.
