Freezes FF after recent update Rated 2 out of 5 stars

I've been happy with this despite the privacy concerns, however since a recent update FF freezes within seconds after it starts. This happens with all my FF installations (2 WinXP and 1 Ubuntu 9.10), Chrome remains unaffected on all these PCs. This has been reported in the forum but it is not acknowledged. Now I keep it disabled until a fix is released, but I'm looking for alternatives. The problem the alternatives do not support Chrome and IE.

This review is for a previous version of the add-on (3.4.10).
