  • I've been using NoScript since at least 6 years ago, when I first heard about it on the "Security Now!" podcast, and don't browse without it! Sure, it's definitely annoying at times but you pay for additional security by sacrificing some personal convenience. A worthwhile trade, in my opinion.

  • Возможности гибкой настройки, блокировки ненужных сайтов. Понятный интерфейс

  • Très difficile à utiliser. Une extension d'experts

  • I have not found anything like this add-on. There have been some frustrations since the new FF Quantum, but they are getting better. I appreciate NoScript and don't understand why so much negativity for a free add-on that does what no other add-on will. Please don't sell out. Keep making this better and safer. Maybe fix this issue where I have to constantly mark a specific same site as Trusted( really my only complaint).

  • This is one of the original add-ons that I actually hunt for when Firefox new versions make it obsolete. Works well with Norton Security Suite+VPN to keep hackers out and privacy in.

  • NoScript is essential and useful but the Android version seems not to have the right click [NoScript] element apparent to allow then management of which sites scripts are allowed. Only atm via the add-ons and preferences whitelist.. that does not work well for knowing which domain a URL is trying to pull. Too many websites draw on 3rd party sites for essential elements than not having this available on the Android version is a nuisance. My impression was that this was available initially and seemed then to disappear.. I don't know if that's a bug or my confusion but surprised that this is a problem.. would be 5* otherwise.

    The menu is there at startup, but it disappears from time to time. To make it appear again, you need to disable and then re-enable again the add-on. If this is what is happening to you, it seems Firefox bug is not quite fixed yet...

  • I love this addon, and use it since many years, but since the introduction of FF Quantum, it's so buggy and hard to use. I hope they'll fix it soon, otherwise I'll have to look for alternatives

  • Absolutely fabulous! Previous to the installation, Firefox was a memory wasting application using a masive amount of CPU time and memory, now my system is running very well.

  • Really necessary.

  • Unlike the old noscript, the new one can only do generic domains. So, there's no way to allow the domain '' when you are at the URL', but block it when you are at a different URL.

    Additionally, the extension defaults to permitting all scripts - which defeats the purpose of the extension. You can only block scripts from a new website after you've already loaded the page, and had those scripts do whatever they were planning to do once.

    Finally, some websites just don't work with noscript enabled, even after using the 'temporarily allow all' function, leading me to constantly have to enable or disable the extension.

    1. NoScript Options > Appearance > Show full addresses in permissions popup.
    2. Nope, the DEFAULT preset (which applies to all the "unknown" websites) has NO script permissions, unless you've changed it from NoScript Options > General > Presets customization
    3. Please report those sites at -- also please notice recent NoScript versions have a new "Disable all restrictions for this tab" command which may help your use case.

  • Noscript has blocked a lot of bad junk even back in the days of when I used windows.
    Redirects and clickjacking and even worse stuff.

    To those reviews who still are angry about past mistakes he made, get over it please.

    Noscript gives your browser rock solid security. This is why I use firefox/firefox derivatives.

    The allow globally dangerous scripts option is a must for newbies and impaitent people.

    Thank you once again Giorgio Maone! This addon is the best I have seen on firefox ever!

  • Great idea, but it ended up being useless to me because the URL field is truncated until unreadable. Adding a way to read the URL would immediately change this to 4 stars for my limited uses. Adding script types/classes/categories as well as URL viewing is closer to what I image as 5 stars.

    EDIT (6/13/18): The URLs mentioned above are those pulled down from the toolbar icon.

    Developer response

    Which URL field? the one in the Options page?

  • Firefox and no script. Love them both

  • It's very nice to block tons of s**t, on different sites, and only watch the content you want.
    I will use NoScript as long as I live, it's a must have, when you want control over harmful scripts, not getting on your PC.

  • 好用

  • Круто

  • Had issues previously with certain sites, tried again now and all my issues appear to be resolved. Thank you so much for providing this important security functionality!

  • Thank you

  • great

  • viel security für wenig aufwand, top

  • A very long time user of this addon, besides Adblock Plus it's first one I installed for over a decade. I installed it on family members computers and it helped mitigate the crap from infecting their computers. Firefox was typically secure but flash and other plugins were a landmine just waiting for you to visit the right website!

    Fast forward to recently and exploitable Plugins are dead, browsers are better secured and advertisements are starting to become regulated but We now have crypto miners, and cpus that can be exploited directly from the browser. Yep, Noscript still has its use.

    The new version of Noscript blocks more than scripts. It functions similar to Ublock, But it has limited control on per sites rules. We should be able to add our own presents, instead of just 3. Which is why I prefer Ublock now because it offers finer control and a more intuitive interface, but you need to rtfm to get the best results.

    Developer response

    "Custom" is how you deploy site-specific rules...

  • If had Chinese language,it would better.

  • Just love it.
    Been with me for so long

  • La version avant Firefox Quantum était plus intuitive et ergonomique.

  • Trekt nog altijd op niks ,in vergelijking met vroeger ! sorry ik verwijder het weer!.
