(In reply to Vladimir D. Seleznev from comment #4) > I just discovered that none of these custom settings are applied on Firefox instances I run. Tracing the Firefox threads show that they do not even read /etc/firefox/pref/. Not sure where the bug is. That makes sense -- as I noted in comment 2, until recently, this has only existed as a snap/flatpak-specific feature (i.e. for those special versions of Firefox), and it hasn't been enabled in official Firefox builds from Mozilla. Starting in Firefox 112 (current beta, going to release next week), though, you can put a JS file in `/etc/firefox/defaults/pref/` with your customized pref values, and that should work. (If it doesn't, please file a bug that depends on bug 1170092 with details.)
