Rated 5 out of 5 stars

It's such a great addon, but it stopped working some days ago. When I hit reply or forward, the signatures don't look as they should anymore. Lots of empty lines, also it looks like HTML paragraph when I hit return or backspace (as more than one new line is created or more than one line is deleted). Also some stuff of my signatures is missing...
When I deactivate the addon everything looks ok with these new lines and deleting lines with backspace. But for sure, no signatures at all.

This review is for a previous version of the add-on (1.3).
