Rated 4 out of 5 stars

Just a reminder to those still using Firefox 3.0.x for some reasons:
The version of 2.0 or above won't work for Firefox 3.0.x.

The keyword can never be enabled in the option panel even for the newest version 2.0.4.

This review is for a previous version of the add-on (2.0.4.1-signed).
