Rated 5 out of 5 stars

The first thing I do on a new Windows PC is install antivirus software. The second thing I do is install firefox. The third....is this extention.

Do not, under any circumstances, use firefox without it. Do not browse the web with a browser that does not implement this functionality. Do not, EVER disable this extention.

The fourth thing....install No Script.

No web site that doesn't work with this extention is worth the risk to your PC or privacy.

This review is for a previous version of the add-on (1.0.beta11.1).
