Editing? Rated 3 out of 5 stars

Thanks for the add-on. Works fine, except I can't get the signature to break down into different lines. It does not appear as it does in thunderbird text/html signature box. Sorry if this is confusing, but I would like it to look like an address with a series of lines, and it appears as an uninterrupted line.
Thanks for any help

This review is for a previous version of the add-on (0.2). 

Works for me without any problems!
I wrote the signature with line-breaks and it got inserted with them. Did you use html-code (<br>)? I did not.
