Rated 5 out of 5 stars

This extension should be integrated into Firefox, it's a shame that I didn't know it years ago. Minor nit, to see their own (or in fact all) compatibility reports for a given extension users have to figure out its GUID. For that they have to find their own profile with the extensions folder, open all GUID.xpi files in this folder with 7zip or similar, view the RDF in these xpi files to determine which extension GUID actually is, and finally enter the relevant GUID into the compatibility report search form. [Disclaimer, this review is for version 1.1 as required for FF 10esr, anything "better" won't work for me.]

This review is for a previous version of the add-on (2.0.1-signed.1-signed).
