amazing: works great, even for my non-standard chat client Rated 5 out of 5 stars

I didn't think it would work for a web-based custom chat client developed internally in my company, but it did! I think this is a better solution than Tab Badge because you don't have to have tabs or windows open or visible in order to be notified.

This review is for a previous version of the add-on (2.11.1-signed.1-signed).
