Rated 4 out of 5 stars

Very simple add-on which does what it is supposed to.

However, would it be possible to override the current Thunderbird sound applicable for both emails and chat such that only the current Thunderbird sound is played upon receiving an email but not a IM.

I explain with a example: when I receive an IM, the sound of the addon that I chose is played, perfect ! However, if I choose another sound in the general settings of Thunderbird, it plays as well.

So what I would like is: a sound set up in the geral settings that is not playing when an IM is received and a sound set up in the addon that is not playing when an email is received.

Thanks a lot !

This review is for a previous version of the add-on (1.1.0). 

Hello, thanks for review. I am not sure, how to do this and unfortunately have no time to figure it. Sorry
