Firefox for Android Support Forum

I am running Ff 114.0.2 on a Windows 11 workstation and Ff mobile on a Samsung Galaxy S20. Syncing is enabled on both devices, but passwords are not syncing, even after manually syncing. Autofill of usernames and passwords works on my workstation, but not on my mobile device, even though that feature is enabled. Sometimes (but not always), I am prompted on my mobile device to unlock Firefox, but after tapping the prompt, nothing happens.

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
