Assegnate 5 su 5 stelle

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.

Questa recensione riguarda una versione precedente (1.3) del componente aggiuntivo.
