Rated 5 out of 5 stars

Great little addon, helps the Mozilla community and addon developers out, plus allows me to enable addons that still work in versions they're not listed as compatible with. Slightly disappointing though when one actually finds out that the addon is, indeed, not working as seems to be the case with most of my addons in 4.0 beta.

This review is for a previous version of the add-on (0.5.1).
