Rated 5 out of 5 stars

I have been using it for months, excellent add-on.
Today (27 June 2011) Firefox website does not list the latest up-to-date add-on by IE Tab+, if you just go on her website, you will find the latest stable release, and it is compatible with FF5.0 and Seamonkey 2.1 !!!

Enjoy !

This review is for a previous version of the add-on (2.02.20110525.1-signed.1-signed).
