Great, could use an improvement Rated 4 out of 5 stars
I like how this extension uses existing cookies, so you don't have to give your user name and password. I'm a bit paranoid about giving that kind of confidential info to a program, so it's a really nice feature that should have been included in other add-ons of this kind.
I do wish the Checker doesn't go sulking - displaying "..." instead of unread mail count, either because of spam or other problems. I hate having to click on it and wait to get the news, since that almost defeats the purpose of having a checker.
