Not sure why, but using Firefox on my iOS to access my Facebook account starteed doing weird things, like confirming cookies, having to login every time and now telling me the browser isn't supported, use the App instead.

Removing Firefox, restartingmy iPhone (XS), reinstalling Firefox and then synchronising the browser on my iPhone with Firefox on my iMac, I still get the same error.

What's going on, please?
