Rated 5 out of 5 stars
MRC Compose is great, but there seems to be a compatibility issue with TB 31. I cannot send e-mails with MRC Compose 1.6 and TB 31.This review is for a previous version of the add-on (1.6). This user has other reviews of this add-on.
Thanks for your feedback. Version 1.6.1 is already uploaded and is waiting for Mozilla final validation. It should be available in few hours.
