Effective browser based Gmail switcher Rated 4 out of 5 stars

If you use gmail regularly and are also a regular internet user you will probably have multiple Gmail accounts. I personally have one for personal use, work and one to absorb spam. This plugin lets you swtich between all you accounts with the click of a button instead of having to log in and log out for each email account.

This review is for a previous version of the add-on (0.5.5).
