Firefox for Android Support Forum

On youtube mobile site or a reddit video, when I click the bottom right button to fullscreen the video, a message pops up that says 'entering fullscreen mode' (with a firefox logo on the left of the message) and then firefox closes and I'm at my android home page

This seems to happen when I watch videos in a new instance. If I reopen firefox to the video and then try fullscreen again, it goes full screen no problem. So basically it's annoying and happens when I try to watch any video full screen for the first time.

Is this a known bug? Wasn't an issue on my old phone (I just got the galaxy s23).

Firefox is fully updated from playstore. Only addons installed is ublock origin and Privacy Badger

Thank you for any assistance

Why does sync break EVERY week on my phone. EVERY week I have to spend half an hour trying and usually failing to get my phone to be able to receive tabs from my desktop computers. Why do you break this critical feature with every update no matter how large.

I restart both firefox on all my devices as well as the devices themselves. I clear cache, cookies and even do fresh installs. Nothing works until a day or so later it magically deigns to function again.
