Output of FF error console after this problem has occured

Having encountered this problem for some time (on and off), it happened again this morning. Someone a while ago suggested that the FF error console may provide useful information; so I attach a copy of mine here. I don't know how much help it will be. I also don't know how much of it is relevant, but I've only had FF open this morning about 10 minutes.

To summarise:

Typing URL and pressing RETURN, ENTER or clicking GREEN ARROW all don't work.
Closing / opening a TAB has no impact (still same issue).
Opening a new WINDOW causes the problem to disappear, but ONLY on the NEW window.
Links that open in a new tab still work OK, as do bookmarks.
