Excellent (until update) Rated 5 out of 5 stars

So useful that it is downright painful to use browsers without something like this installed.

It does get annoying when Firefox updates and it complains about AiO being incompatible. I just updated to FF8 myself, and AiO worked fine until the next session when Firefox actually checked add-on compatibility. (Most AiO updates these days are just to slap on new version numbers in its config file! You can get by with a little tinkering in its install.rdf file.)

This review is for a previous version of the add-on (0.22.1.1-signed.1-signed).  This user has 2 previous reviews of this add-on.
