Fantastic extension, works EXACTLY LIKE IT SAYS Rated 5 out of 5 stars
This is a fantastic little extension for those of us who have read the description and are using it properly. The description currently states: "Help Mozilla make sure your favorite add-ons get updated for upcoming Firefox releases by using this extension to report whether they still work or are having some issues with alpha and beta releases. Note: Recommended for alpha and beta users only!" In other words, they emphasise THREE TIMES that this add-on is NOT designed for use in current versions of Firefox!
If you really want to make all your extensions work, and you've used about:config before, make a new Boolean pref called extensions.checkCompatibility.7.0 and set it to false. Every 6 weeks, make a new one with the version number incremented (e.g., the next is extensions.checkCompatibility.8.0). Try reading http://kb.mozillazine.org/Updating_add-ons for more info.
