Just what I need Rated 4 out of 5 stars
Thunderbird's text editor lacks the abiity to re-wrap text. With this add-on I can now edit my mail without linebreaks. Only before sending I hit ctrl-shift-w. Does just what is needed!
Hint for those who write html-mail: don't do it: Using html is risky because your mail can be blocked as spam. Spammers use html and spamfilters block html.
