Same thing happened to me when I upgraded to firefox 4. It seems the freecorder tool bar isn't compatible with the upgrade. But freecorder is compatible with internet explorer. You can activate recording from the freecorder tool bar on explorer and because freecorder records any sound coming out of the computer, it'll record any sound streamed to firefox. It's a bit of a hassle having two browsers running at once but if you're like me and prefer the firefox environment, I guess we'll have to put up with it until freecorder becomes compatible to firefox 4.

Nope, not gonna do it!! I will revert back to previous version. Latest and greatest browser is not worth giving up the freecorder toolbar. As long as it works, I don't care what browser I use.
