Great. I love it more and more.
But -
Please allow sound alerts. And fix the mark read/delete/archive bug.

Still somewhat buggy Rated 4 out of 5 stars

I still like this add-on, but:
- It still doesn't actually delete mails on GMail. Weird.
- It marks old mails as new (with a popup) once a 'new' mail is deleted (from GMail, obviously, as it can't handle the deletion by itself).

In short - needs a new version. Badly. But good all the same as a passive notifier.

Great idea, needs quite a bit of work.
As mentioned before:
1. It really needs a popup notification (like the original Chrome extension)
2. same for sound notifications
3. Popup mail control doesn't really seem to work, it seems.

Please go on working on this, though, as it's potentially far better than other GMail notifier extensions I've seen for Firefox.
