Rated 1 out of 5 stars

The concept of this addon is noble but the implementation is pathetic and awful. It causes random and numerous crashes, it slows down the browser, litters the preferences with excessive entries, has no support or way to reach anyone to report problems. I would stay away from this until they get their act together and fix up. They are using this to drive traffic and attention to their other services and don't really give enough attention to developing it for itself. Real shame.

This review is for a previous version of the add-on (1.314).
