This did not work for me in FF 22.214.171.124. Installed ok and button worked but nothing was blocked & no thing appeared in js console 'Messages' tab. Your mod may be incompatible with another (of many!) addons as the one by original author works. Thanks for working on this!This review is for a previous version of the add-on (1.3.2).
