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.

I'm notified every time WebGL is blocked on each page load. There's no way to disable these notifications and it's very irritating.

Edit: updated to 5 stars as it can be disabled after all but the setting isn't described very clearly.

it's 5-stars, because it's little time and effort to manage and also Edward Snowden said that noscript is the best protection in the whole internet...(after some Firefox update, noscript does seem to block internet in Firefox,,, but I'm sure there will be a workaround in the next edition ... buona vacanza)

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

No Script is an incredibly useful add-on. In the past, I'd have given it five stars; it now gets only two (see issues below). All in all, I'd say it's still better to have it than not, but that's only because there is no better alternative, and there is no difference between having to completely disable it on a page versus not having it at all.

First of all, it would have gotten three due to the issues I list further down, but it gets two because of a major functionality problem that makes it obnoxious to use, and by its admission, not private in private windows.

In the past, when you set it to trust top-level domains, it would automatically set them to temp trusted; however, for whatever reason, it now sets them to "custom," for me, which functions the same as untrusted, and changing it doesn't even refresh the page for you.

The default setting handling is a huge inconvenience, but that is not where the problems end. You cannot restore previous functionality by manually setting the top-level domain to temp trust. To enable scripts on the page, you must set it to trust, which makes it permanently trusted, and keeps a log of every page you visit in private windows. If you try to change it to temp trust and refresh the page, it goes back to "custom."

Besides that, the description for the extension is outdated. Not only does it still mention Flash, but it also claims no loss of functionality when you need it, which is not true. In most cases, enabling some scripts will return the functionality you need, but there are several reasons why that's not always the case.

Sometimes, certain scripts you need will be on sub-domains of the top-level domain, and they need to be enabled separately; however, NoScript doesn't show them because it thinks they are part of the main domain, so you have no way to make the site work without completely disabling the addon for the page.

In other instances, sites won't load all the scripts until they load some other domains. For example, a CDN containing vital scripts might not appear on the list because it's called after an analytics script has run. There is no way to know that unless you enable each script on the list, one by one. The domain doesn't need to be related; it's just something about how the page loads.

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

He notado en las demás reseñas, que las personas no parecen comprender el propósito de este addon. La idea es que bloquee los scripts, si una página se rompe por ello, es algo perfectamente esperable, no es culpa de la extensión perse, sino de quien desarrolló dicha página web, queda a tu criterio si lo quieres añadir a la lista blanca o no. Lo realmente triste y reprochable, es más bien que hoy en día hayan tantas páginas que quieran que actives los scripts si o si para poder usarlos, incluso páginas que no los necesitan para nada.

El abuso de los scripts y la manía de convertir las páginas web en "aplicaciones", es lo que ha causado que ahora usar el navegador implique un consumo cada vez mayor de RAM, sin contar los riesgos de seguridad innecesarios del uso de scripts, tanto para el usuario como para el webmaster/desarrollador. Así que por mi parte, prefiero que se rompan las páginas que sean, no les voy a activar los scripts si no son páginas que hagan un uso inteligente y justo de ellas.

It give me the power to control every script on every sites.

This add-on works as intended and has saved me from a lot of potential problems and annoying website antics.

The best!

Completely breaks reddit on mobile, site becomes unusable. I only got it for help blocking reddits creepy tracking bs on this browser.

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.
