Earl Rated 1 out of 5 stars

I've tried it 4 times(1 on mobile). Lousy experience. First time I quite was because in completely messed up all my bookmarks, totally. Always cause Firefox to crash.
Could be a good one. Don't waste your time(and effort). I won't be back this time.

This review is for a previous version of the add-on (4.1.3). 

Freezes Firefox 4 or later Rated 1 out of 5 stars

Initially, I liked it. After Firefox 4 upgrade it freezes all the time. Only fix is uninstall.
Spent hours trying to fix but gave up. Both laptop & desktop are effected.
