This add-on is great! Does what it says. Blocks all scripts and embedded materials. And since almost all ads (like those from doubleclick) use scripts to load, this program blocks all of the adds too!
Sure some might find it annoying to have to approve every website you visit, but that's the whole point! You don't want malicious scripts doing any damage. Besides, anyone can easily circumvent this by adding frequently visited websites on the safelist (to allow every time), so you don't have to click every time you load the page.
