Suddenly doesn't work Rated 4 out of 5 stars

I have Win 7-64 bit,FF11.0,and recently,MWB has just stopped working.Am I the only one experiencing this? I really miss this add-on!
Update: I reinstalled MWB over the existing add-on,and it's working again!

Seems to work with FF3! Rated 5 out of 5 stars

Is this a new release that now works with FF3? I'm not sure,but I tried to install it,and it worked! Fantastic,I've got my MWB back!!

This review is for a previous version of the add-on (0.2.9).
