Rated 5 out of 5 stars

excellent addon, easy to use even I know only a little about html, exatly what I need. There are some little problems with the new version, maybe it's just me. After automatically updated to the latest version, my old templates are gone and I had to write them again.......and for the forward quote, the original quote can't be completely hidden, you can still see "original message" behind your own made quote. If you can remove that too, it'll be great. But I'm happy with this addon, so 5 stars.

edit: Thanks for the answer, did what you asked for, please check bug ID 25089, error console descriptions are within.

This review is for a previous version of the add-on (0.9.1). 

First of all thanks for the great review - however when updating, Thunderbird should have prompted you with a conversion window:

this would have made sure to migrate all your old settings. As regards the other problem, could you please raise a bug with a little more details here:

I would be very interested whether you get any warnings or error messages in tools > error console when opening the message composer window.
