GMail has definitely changed a lot of our lives. GMail Drive, 2 Gigs of space, and integration with Picasa application. And then along comes THE manager for GMail accounts through a browser. Wow!
The GMail Manager extension enhances Firefox by providing the current email account status on the bottom of the status bar. Not only will it display the current email account, you can also manage multiple GMail accounts.
The extension also has support for GMail hosted accounts, the ability to import/export existing account preferences, and one-click access to your GMail account.
One of the key features that makes this extension worth owning is the top 10 emails displayed in the tooltip when hovering over the email account in the status bar of the browser. Excellent feature and it doesn't even require a trip to GMail.
The GMail Manager is worth having if you are really busy, because it even incorporates a notification when you receive a new email. Sweet!
This extension can only get better from here on out and deserves a rating of 5 out of 5.
