Hi there I experience an issue with Firefox on one of my computers only. Windows 10, just updated to version 92.0 (but to be fair this is an issue that lasts for years now). I cannot receive any Tab from my other computer or smartphone, nor can i share (i don't see the option in the list when i right click on a tab). Of course it is connected to sync with all my other 4 devices. Maybe there shall be some "user preference" on that specific computer that should be reset ? Thanks in advance for giving hints and leads, hopefully that should not be too serious.
