Keazen oplossing

You are in luck as the minimum requirements for Firefox on macOS since Fx 116.0 has been macOS 10.15 so you can use the current Firefox 131.0 Release from https://www.mozilla.org/firefox/all/desktop-release/osx/ as just pick your language and download and install the dmg.

Bewurke troch James op

Well thank you so much James.

FYI in my experience this isn't true. There's been a bad bug on Catalina for several releases now, where many of the menus don't work (settings, bookmarks, translation, manage extensions, update reminders). I assume it's all the same component.
