ESSENTIAL! Rated 5 out of 5 stars

What more can you say, blocks EVERYTHING. Sure it's a bit of a hassle at first to buildup your whitelist, but I recommend this as the #1 extension for security. It's awesome for everyone from geeks surfing questionable sites - to civilians who have trouble locating the address bar. Test it out using FF3RC1 Portable.

The only word of warning, is that it's a manual layer of security, so if you add something bad to the whitelist, nothing's going to tell you not to.

I can't speak to performance or memory usage much, but I don't see much of a hit. Page loads however are dramatically faster sometimes, as even the most reputable sites have 6 or 7 different things loading in the background from various domains.... Unless you're running NoScript :)

Good Idea Rated 3 out of 5 stars

Its a good idea, it can just get annoying...

It would be better if the add-on would have a list of good websites and auto-trust them. This would be easier for new users of NoScript.

Great Functionality Rated 4 out of 5 stars

This Add-On does what it's supposed to, and while that doesn't seem like much, it really is something for an extension, as many fail at their objectives. I really enjoy the fact that I can allow or disable scripts coming from different sites onto one page, so I can, for example, allow Facebook's scripts but block it's advertiser's banners :)

Great extension, only reason I didn't give it 5 stars is because esthetically, it is less than pleasing. Just get some nicer icons and you'll have yourself a perfect extension.

Too proactive. You have to enable each and every script. I don't recommend it.
Reloads for every website and every script that you allow. My downloads became slower on sourceforge.net even after enabling all scripts on it.

Perhaps it needs a "list of safe sites" feature like adblock plus has so that certain trusted sites are enabled by default to run scripts.

NO SCRIPT w/speed issues Rated 5 out of 5 stars

NO SCRIPT, may (not in all cases) make your browser slow, just install FASTER FOX I use it, it makes my browser like greased lightning.

Must have..... Rated 5 out of 5 stars

Without doubt one of the best add-ons for Firefox this little beauty has vastly improved my browsing speed and security and should be a must have.

A little disappointed quite a few users have complaints concerning the annoyance of continual alerts when it's hardly rocket science to disable them and only white list when it's needed or pages, components appears to not load correctly.Chances are if you don't notice it you don't need it, if you do it's a one-click fix every so often.

Many thanks to the developer for such a vital add-on.

Thank you! This program does just what I want it to. When I visit a web-site clicking on the options button at the bottom of the window allows me to choose which content to allow. And for how long. Not being an advanced user I appreciate how easy this is to use. Keep up the good work! Jim

Grazie Giorgio, con NoScript è stato aggiunto un'altro mattone al muro della sicurezza del nostro browser.

Wow! The Internet really is a safer place with NoScript. Instead of surfing around with Firefox opening every random site's unsafe javascript and flash or java controls, you can now whitelist the sites you do trust. Genius, and all can be done via the icon in the status bar, nice and easy!

This addon is best used with CS Lite so that you can whitelsit cookeis also, giving you anonymity for untrusted sites too!

sigh Rated 4 out of 5 stars

I've used NoScript for virtually as long as I've used Firefox. I hate the idea of not using it. I've spent hours tweaking it to fit my needs. But sadly it makes ff run like a snail. I've checked and checked again, and it is clearly NoScript that causes the problem. This is sad, cause if the memory problems were gone it would be the greatest extension of them all.

If your system can handle it, then by all means use it. If it can't, hope that the issue goes away soon.
