Rated 5 out of 5 stars

It redirected the messages but the messages arrived at their destination in what looked like "source format".

This has been fixed!!!! Yeay!

This review is for a previous version of the add-on (0.1). 

I've fixed this bug in the next version, it is now in the mozilla line for the preliminary check. You can download it directly from www.irkit.ru.Thank you for review!
