Rated 1 out of 5 stars
This extension does not add any menu item and hence it is not at all apparent how to use it.
Firefox is in urgent need of a plugin such as this, but at the moment this particular extension does not deliver.
To the coder - I hope you won't be put off by this comment, and that you will continue to develop the extension to its potential. I will certainly increase my rating if you are able to do this.
