Great ad-on for Firefox

[klinger]

Tired of re-formatting because of malicious scripts that even the best software can't remove? Then you need THIS. It will not allow ANY script to run unless you approve it. It then remembers the webpage and you will never have to re-set it when you go there again.

I've used this add-on for ages, an invaluable tool!

I covered that very same add-on in an earlier thread I've made.

I've been using it for awhile, and I think it's quite cool. One thing that Klinger failed to mention, is that it's possible to temporarily allow something if you want.

The temporary permissions can either be revoked in the right click menu, or when you close the browser (and thus end the session).

Get good Anti Virus and use it evey day.
