Great improvements in version 3 Rated 5 out of 5 stars
Great, especially with the update to version 3 which improved usability a lot. Many of the things I wished for got fixed or added. Doesn't hang on my system: FF 25.0 and OSX 10.9This review is for a previous version of the add-on (2.0.20). This user has a previous review of this add-on.
