Rated 5 out of 5 stars
Not a huge fan of the new location of the compatibility data, but I'm going to assume it was changed to accommodate future versions of Firefox. In any case, add-on now works once again as expected; therefore, five stars for you, sir.This review is for a previous version of the add-on (0.5.1).
The new location was more to keep the information "out of the way" than anything. With 4.0's extension manager rewrite, extensions' titles were given a large font, and it felt rather silly to put such low-priority metadata alongside the title in that case.

This add-on, while technically "compatible" with the versions in question (in the sense that it still does what it says on the tin), causes Firefox to freeze for several seconds when the Add-ons Manager is opened in v6 and above. I'll gladly upgrade my rating to five stars when this is resolved.This review is for a previous version of the add-on (0.4.20110114).
