Rated 5 out of 5 stars

0.8 still works nicely, but it messes up the status bar and renders it unusable. – Find me on Twitter @GerZah and I'll send you screenshots. If you want me to test beta versions, let me know.

This review is for a previous version of the add-on (0.8). 

Hi GerZah,
This problem is now fixed in version 0.8.3. It seems that the code to check if the Mail Redirect button should be enabled was called to soon during start-up, causing this problem. I've added an extra check and this should work again.
You can download version 0.8.3 from the developers page or from the mailredirect website.
