Rated 5 out of 5 stars

I tried it on Earlybird 47.0a2 (2016-03-22)
not working.
I just run ahead the schedule. Thanx anyway! Such a tiny thing, but so necessary!!!

This review is for a previous version of the add-on (0.8.7). 

Hi, thank you for your review! I've uploaded Mail Redirect 0.8.8a1 which fixes this issue. Since you're ahead of schedule I guess you don't mind too much running a alpha version… Go to Mail Redirect on addons.mozilla.org and click on Development Channel on the bottom of the page to download the new release.

Version 0.8.8a1 contained an error for Thunderbird 38 and lower, so I released 0.8.8a2…
