After further testing it's not a Firefox problem, other applications have the same issue. Weirdly, gnome-shell itself doesn't have the issue, hence my initial mistake. Gnome terminal, thunderbird, and Ubuntu software all have the same symptoms.
Note that mouse input works fine. Reaffecting to gnome-shell as it seems to be a problem there? ** Package changed: firefox (Ubuntu) => gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1940657 Title: Cannot type in address bar nor page content in live session Status in gnome-shell package in Ubuntu: New Bug description: While testing the focal 20.04.3 Ubuntu Desktop iso, I tried to launch Firefox in the live session, but was unable to type anything to either the address bar or the content of the homepage (with a text box to search stuff) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1940657/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
