Firefox Community Forum

I have a MacMini M2 with the current Sonoma os. Firefox has been updated. Frustrating. Yet prime videos won't play and get this notice:

"Mozilla Firefox update required A later version of Mozilla Firefox is required for Prime Video. To update, click the menu button (three horizontal stripes) on the web browser toolbar, click Help, About Firefox, and then click Restart to update Firefox."

When I click on Firefox, the top menu bar is dimmed. When I click on New Tab or New Window, nothing happens. I've downloaded, reinstalled and updated the latest version of Firefox but it doesn't work. I've also clicked Option when opening Firefox. I click Refresh Firefox and it works but when I quit and restart, I'm back to the same problem again.

Yesterday I could open any or all of the downloaded apps on the screen of my Apple laptop. Today, I can't! WHAT IS GOING ON? Being elderly and not very techie (to say the least!), I need simple answers, no jargon please. Is it because my laptop is 'elderly' in tech terms (Catalina 10.15.7) or what? I've used Mozilla most of the time for very many years, but I might swap to Safari or Chrome instead if this isn't sorted out PDQ.
