This is my favorite Gmail extension for Firefox. I do wish it would play an alert sound upon receiving new mail.

Seems to have font problems on Windows and I'd like to be able to hide the addon bar icon (I use Pentadactyl, so I can't really just hide the addon bar), but other than that, perfect! Exactly what I've been looking for since I moved back from Chrome - and obviously, could no longer use Google Mail Checker Plus.

Good Rated 5 out of 5 stars

I like it a lot. For me it's much better than the competition. Being able to see the email subject and sender are especially useful. (Works fine in firefox 11.0, ubuntu 10.10, x86-64).
Many thanks to the developer

Great add on its simple yet very useful also can i ask for a feature maybe make it so if you double click the icon it sends you to the inbox that feature would make this add on perfect in my book and shouldn't be hard

Nice Rated 4 out of 5 stars

Hi, thanks for a nice tool!

Two requests though.
1. Mail delete isn't working for me (Firefox 7)
2. Feature request. Once the pop-up window is open with the mail overview, could you include a refresh email button next to the 'compose mail button'?

Google Mail Checker Plus was the reason I didn't move from chrome to Firefox. It just saved so much time. Thanks for making a great equivalent!

"Only" four stars because it is so easy to quit the chat. You should use a small icon (like in gmail) to quit or switch to the gmail site instead of all the bar... it irritates me &gt;&lt;, so I never use the chat.
EDIT : could you make the popup draggable instead to have a link on the title bar
