Форум спільноти Firefox для Android

I have been using Firefox on both Windows and Android phones. I recently lost an S-23 to a virus. When I was setting up Firefox on the new phone I got a message that Firefox had detected the Vezeen virus on the old phone and the new phone. I immediately cleared the history and cache but the message still remained so I uninstalled Firefox.

 Vezeen is identified as a phishing virus and the effect on the old phone was that it switched from site to site so fast it was almost impossible to put commands into the phone. I traded the old phone in so it is impossible to know if it has been thoroughly scrubbed.
  Thus far I have seen no effect on the new phone or Windows device.
  Suggestions?  Open a new account or what?  I have tried swearing with no success. I am going to leave Firefox off Android devices until I have more confidence.

Firefox still eating too much RAM when to many tabs are open, optimisation would always be welcome naturally.

But maybe also looking into something like a system, that puts certain tabs that haven't been used for a long time into something like a sleep mode?

When I connect my Bluetooth earbuds to watch a video on Firefox browser it works fine. But when I disconnect my Bluetooth ear buds the video stops playing and cannot be played through the phone anymore.

I refresh the page, choose another video, close the tab, open a new tab and now the video does not even play at all.

When scanning the QR code, my phone is stuck on this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-54-22-6b261a.png While my desktop shows this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-55-00-1c9ca2.png

When signing in with email on my phone, I get an "Unexpected error": https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-56-18-5c7b93.png

I've tried everything. I've cleared the app's storage and also re-installing the app. I've removed the old device login from "Connected Services" in https://accounts.firefox.com/settings.
