Addons marked as compatible multi-process.. but are indeed not. Rated 2 out of 5 stars

Add-on Compatibility Reporter mark some addons as : "Compatible with multi-process" but, however, some add-ons are actually NOT compatibles, like, say, FireGestures or Firebug (about:support report that "some addons disabled multi-process").

This review is for a previous version of the add-on (2.2.1).
