Rated 1 out of 5 stars

It can't be deleted once you have installed it. It hasn't the buttons "Disable" and "Delete" that all other add-ons have.

This review is for a previous version of the add-on (1.7.1). 

By design

This addon would not offer much protection if it could simply be disabled. To remove it, start Firefox in safe mode and disable all addons. It can then be removed from the addon manager.
