Rated 2 out of 5 stars

Brilliant idea. So close to being my new email client, but just too buggy:
- notifications are ugly as sin;
- sending claims to succeed even when there is a server error (eg. invalid password);
- tab behaviour in compose dialog is frustrating;
- I don't use any addon that forces new tabs on me.

This review is for a previous version of the add-on (2.86.3.1-signed). 

- notifications are ugly as sin : there are three types of notifications .... three types of sins ..
- sending claims to succeed even when there is a server error (eg. invalid password) : ???
- tab behaviour in compose dialog is frustrating : there is an option to compose mail in a window ....
- I don't use any addon that forces new tabs on me : I do not force anyone!
