One of my "must have" addons Rated 5 out of 5 stars

I first discovered this addon when I found that I really needed to be able to switch very quickly between my gmail accounts. This addon provides the functionality I needed. This could also be useful if you have multiple identities on some website, or if you just want to keep cookies from one site (for example, google) separate from the rest of your web browsing. I commend the developer for continuing to work on this addon, so that it works with the latest firefox.

This review is for a previous version of the add-on (13.4.331.1-signed).
