Rated 3 out of 5 stars

I love having a spellchecker! BUT, there is a problem which drives me mad - every now and then, usually when I've just finished writing a long email, the spellchecker freezes Thunderbird completely. I have no option but to restart, and then of course the email is lost. Every update i hope this will be fixed - but no. It did it again yesterday. Has anyone a work-around? Please?
And by the way, I see no way to post a bug report for this problem, and it doesn't seem to have been updated since 2010. Is there no other spellchecker around? It is such an essential part of writing emails!

This review is for a previous version of the add-on (5.0.1).
