Komunitné fórum Firefox

Is there a preference in about:config to fake or simply block websites from reading the font-list of my operatingsystem? I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

When logging into my financial institutions website it reports back that I have version 91... of the Firefox browser installed and that it isn't supported. I actually have version 101.0.1 as reported by the browser itself. I called them and they asked me to check my version of Firefox by using www.whatismybrowser.com and it reports back that I'm running version 91. Can you help?

Anyone know if there is a way to import Google Chrome extensions into Firefox. I am moving over and want to make it easy. When I search all I get is bookmarks which I know how to do.

TIA!

Can websites i visit track my browsertheme for example system default or light or dark theme? I like the dark theme but i'm not using it because i fear it makes my browser much more unique, is that so? If so, is there a preference or another way to prefent websites from tracking my browser theme?
