Rated 5 out of 5 stars

Great extension!

Very useful in e-mail threads involving people from countries, where the standard 'Re' and 'Fwd' prefixes are translated into native languages. This extension allows to keep the subject clean without a stack of 'Re' prefixes in different languages.

It seems to be working with Thunderbird 5.0 after adjusting the maxVersion value in install.rdf. No problems noticed so far.

This review is for a previous version of the add-on (0.4.2).
