this is almost certainly a stuck grab. If FF has an active grab, no other
application can receive pointer events for the duration of the grab. 
You don't actually need to reinstall, usually restarting X is enough. In
fact, making the FF window unviewable will break the grab too (e.g.
minimising it)

This may be an application issue or an issue with the server. To figure out
what exactly happens, we'd need a reproducible test case - stuck grabs are
notoriously tricky to debug.
