Firefox 29 users get v.2.4 Rated 4 out of 5 stars
As of May 2, version 2.4 is the one that is working for me on Firefox 29. This isn't the "approved" version (the one that shows up at the top on the main addon page), which is 2.2 atm. You'll have to scroll all the way down to "Version Information" and click on "see complete version history."This review is for a previous version of the add-on (2.2.1-signed.1-signed).
