I've been using this *must have* addon for years. I also recommend the AdNauseam adblocker, which is so good that Google banned it. Unlike other adblockers, AdNauseam doesn't prevent content providers from getting paid because the addon silently clicks on the ads it blocks.

NoScript is an indispensable extension for browsing on sites that do not provide a satisfactory user experience with excessive ad scripts and popups. Unfortunately, because it is so advanced in its capabilities and its possibilities, it can confuse rather inattentive users like me. The option I judged no longer works as it was before, is actually available in a different way in this new Firefox extension architecture. I want to leave here registered how patiently I was answered and attended by the developer in broad daylight on Sunday. My big thanks to Giorgio Maone for his competent extension and his unconditional support.

Das WICHTIGSTE und beste Add-on für den Firefox!!!
JavaScript, Flash, Java und andere ausführbare Inhalte nur auf vertrauenswürdigen Domains meiner Wahl zuzulassen ist schon eine feine Sache!

love this app

Most of the UI issues and whatnot are fixed now that the WE growing pains have subsided. The menu is still a bit slow to open, maybe because of the graphical elements, but that's not a huge deal.

At the end of the day it's absolutely essential to run this if you're at all serious about security.
