Review for Is It Compatible? by George Yves
Rated 4 out of 5 stars
I support bwProductions:
"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."
To create your own collections, you must have a Mozilla Add-ons account.
