Rated 3 out of 5 stars

I like this extension, but I'm kind of confused at how you went about it. Wouldn't it make more sense for Thunderbird to choose a slave client (in my case Firefox)? Whenever Thunderbird received new mail, it could push the notification to Firefox, instead of Firefox polling Thunderbird constantly at an arbitrary interval. If Thunderbird did all the heavy lifting then the notification in Firefox would be instantaneous.

Also, I hope you plan to update this for Firefox 4, as I can't seem to get it to work.

This review is for a previous version of the add-on (2.1.9).  This user has a previous review of this add-on.

I have recently downloaded the beta version of Firefox 4.x. Not only do I not like what I see for personal use, but I also find that there is need for significant re-write of this addon making it very difficult to preserve backwards compatibility. For these reasons, at this time, users should NOT count on having this addon updated for Firefox 4. My apologies.
