WARNING! Causes crashes with SEVERE data loss. Since mid 2025, this extension regularly causes the browser to crash. It can even crash the browser so severely that windows freezes irreversibly, with SEVERE data loss as a result. The crashes stopped when I deleted this extension, and re-occurred after reinstalling it. Several others have reported the same issues on user forums.

It's not working.

ok its a good security 4 ur browser but now the web is so slow that i cant even play a game on poki 💀💀

Esta vaina debería tener un modo automático para aquellos que no saben de programación.

One star for SidebarUtil.tab.js

Disruptive as hell and for what? Why do you need to know if I have a sidebar open? I don't even know what a sidebar is. Remove this nonsense.

I really wanted to use NoScript. I prefer single-purpose extensions that focus on doing one job well, compared to more multi-purpose extensions like uBlock Origin.

However, I ultimately couldn't stick with it because the user experience did not suit my needs.

E.g. one mobile screen presents around 12 different icons packed into the height of 3 lines of text, leaving a large portion of the screen completely empty below them.

My main frustration is that none of these icons have labels. Expecting users to learn and memorize the meaning of a dozen different unlabeled symbols creates an unnecessary barrier to entry and makes using the extension quickly and efficiently very difficult. It feels counter-intuitive to leave so much screen real estate blank when that space could be used to label each icon and explain its function.

uBlock Origin is easier to use than NoScript.

A terrible extension! Blocks nearly all websites not allowing some to work even after marking all scripts as trusted (meetup.com for example). I tried this for several weeks and would never install it again.

Since Firefox 134.0 (64-Bit Linux) (or newest NoScript 12.1.1?) my main profile is broken. I see only blank pages, as long as NoScript is active, and no way to configure.

For me it mucked up Firefox, giving me "Enable Firefox" (already enabled) and forcing Firefox to ask for permission to open each site. I mention this to give the head's up. BUT as someone wiser said, it's "an awesome addon, [but] you have to be extremely careful with it. It can really mess up your web experience if you don't know how to use it."

It breaks YouTube even if it's trusted.

My review was removed. The latest update removed all settings, all sites that were whitelisted reverted to default i.e. untrusted, a hassle to restore since so many sites have a ridiculous amount of domains with cdn's and whatnot. I have now disabled automatic updates of this add-on because some (most) devs don't care if an "update" wreaks havoc as long as they get to constantly change something in their code, "if it aint broke, break it!" as their motto is.

It works great if you want to type a search in the search bar and expect NO results, just a blank page. Also youtube will not work at all with No Script Security Suite turned on.

It was OK for years. I trusted FedEx but it will not load now. I am unable to see when a package will be delivered. Saying it is a privileged page and I can't change it. I'm going to uninstsll it. I have to be able to see these pages so nosscipt is now nomore.

NoScript is a nice idea on paper but actual use is such an effort that it exceeds its apparent benefit. This app needs a feature so that the community of users can contribute to what features on a web site need to be refused and which are acceptable. For each user to have to go over this mountain of work is rediculous.

Settings lose after restart if duckduckgo installed.

Totally broken since the last update, I switched from release to ESR because I couldn't find the issue why Firefox became unusable after a few hours getting slower and eating up resources like crazy. In ESR I still had the issue that refreshing a page resulted in a lot of pages displaying without CSS or JavaScript looking like they're comming from the 90s, after a few days.
