So why use it ?
Security rule is working like that :
all is blocked by default if it's not known as a safe source.
all the rest must be blocked until you know it's safe.

Excellent to block sites that use auto-refresh, and even to block paywalls on badly programmed sites. Nice and easy.

It does block scripts form complete domains nicely, but lacks the feature to block on specific *pages* but not others of the same site.

Simply allowing to match more elements of the path would be a very easy to implement solution. Then we could block scripts on, e.g., https://www.google.com/search? while allowing them on https://www.google.com/maps/ .

Even better would be the use of regular expressions.

I downloaded this while looking for an add-on to block particular scripts, but was disappointed to find that it only supports blocking scripts on an entire domain. This might be useful for some limited purposes, but to be of much general use, it really needs the ability to block specific files, or paths that match regular expressions perhaps.

This is a very simple addon that does one and only one thing. I like simple. The last thing I need is to have to navigate through a dozen screens and hundreds of options when there is only one I am interested in. This is exactly what I was looking for and it does exactly what it promised.

Right after I download it Firefox went crazy! Only page that still worked was Yahoo, wattpad was broken (trying to work on my story) and it bacake a wall of links that were pushed onto the left side, any sites that did work links had to be double left licked to get the link to work. After several hours of this headke finly find in Mozilla support a mention of some kind of plug in being disabled. Not knowing where to go I went to addons and hoped that the plug in the guide was talking about was in there. No, but saw that ALL of my browsers plug ins were disabled. They sure as heck were not before this! Stay way until this author ether proves his add on is not malwhere or Mozilla comes and says something about this. Until then Run!

-No wildcards support.
-No clear indication of what is blocked and what isn't, unclear how it works (if does at all) with cross-domain scripts.
-No blacklist import/export.
-Apparently works only with HTTP.

Don't waste your time with this.

I normally use "Adblock Plus" and "Adblock Plus Pop-Up Addon" to disabled annoying pop-up ads and other unwanted advertisements, and it works well, but some sites that I visit still have javascript popup ads that manage to sneak passed Adblock Plus.

I searched for other Ad block programs, but none worked, but then I stumbled across "YesScript" and figured I would give it a try. Using the "YesScript" addon options, I added the website address to a black list and then tested the site and it worked great. The site functions perfectly and there are no javascript pop-up ads at all.

This is a great addon for Firefox. I highly recommend it.

Thank you :)

An interesting plugin. I didn't knew that there were malicious scripts before this.

Fantastic, using this on culture website "the apricity". If its working there it can work anywhere. thanks. Wanted to use only on that particular website and it is possible with this addon.

I used this script to temporarily block a site. When I tried to then remove the site, the block still continued. I tried uninstalling the add-on, and it still blocks. I've deleted my prefs (which was frustrating and prompted me to upgrade even though I was already upgraded) checking config, etc. I now have to do a complete reinstall of Firefox. I've lost all of my open tabs, including what I was working on in them, and all my other extensions. I'm going to lose everything and have to start all over, including reinstalling all of my applications that have Firefox extensions, just to read my email.

This Product is excellent for turning java on and off on websites that are troublesome or known malicious websites. Also works like a charm on my Seamonkey 2.22.1 Five stars.

Perfeito o complemento, a muito tempo eu havia excluído o NoScript porque ele atrapalhava mais do que ajudava.
Este complemento do YesScript é ótimo para desbloquear sites que não permitem copiar seu texto.
Basta adicionar o site na lista negra e fazer um refresh (F5) da página. Já está pronto para copiar qualquer coisa desse site.
Parabéns pelo complemento 5 estrelas pra vc!!!

tl;dr: While the add-on itself doesn't have any inherent flaws (aside from a couple features that are on peoples' wish-lists), there are some inherent flaws in Firefox that cause me to keep using NoScript. There is only one real issue with the add-on, and that's just a simple oversight in the concept.

First off, I recommend this add-on if you want some much-needed security without having a complete lock-down like NoScript does. (although I personally prefer NoScript). I just feel the need to point out a couple flaws that make this add-on less effective. Sadly, most of these flaws are inherent to the browser itself, rather than the add-on. Also, please donate to the developer, Jason Barnabie. He did his work, and he deserves the support.

As a staunch advocate of Firefox, even I'll admit that it's fallen way behind other browsers in security (even IE in at least one case). For example, Firefox doesn't use the modern Windows feature called "low integrity mode" or "protected mode" to run the browser process(es) with as few user permissions as possible. Basically, what the Protected Mode does is that it makes anyone who finds a vulnerability in Chrome or IE also have to find a way to get out of the security sandbox and gain access to the rest of the system (as a lazy coder, that would deter me automatically). The feature has been around since Windows Vista. Mozilla's still working on "low-rights Firefox" mode, and there's no indication of whether anyone is working on implementing sandboxing for the desktop version of Firefox.

In short, if a site happens to be missed by the blacklist used by this add-on, Firefox is somewhat more vulnerable than the other popular browsers. Someone who finds a vulnerability in Firefox doesn't need to find an additional vulnerability in Windows, as they would with Chrome and IE.

There's also the issue of someone hijacking a trusted site and injecting malicious code into specific pages (such as a log-in or signup form, the landing page, or other forms). While whitelisting also has this vulnerability for any whitelisted site, blacklisting has it by default for any non-blacklisted site. In addition, blacklisting might not always keep up with the current malicious sites, while whitelisting will at least offer a first layer of protection against new threats. NoScript also supports temporarily whitelisting a site, which is what I primarily use unless it's a site I use all the time (and even then, only if they use https). This is really the only major flaw in the add-on (and it's really only just an oversight that's easy to make).

From a basic user standpoint, this is a really good add-on if you're careful on the web. However, as a software security guy who occasionally has to venture into the unknown, I will continue to use NoScript.

It's not particularly impressive; blocks java entirely, and disable does not seem to work, forcing the user to delete the blacklist. Not being able to select a specific piece of javascript for removal is particularly annoying. Definitely not suitable for day-to-day use.

I've often thought it would be nice if NoScript defaulted to allowing all sites, just found this addon today. Simple and works well, but as JSJimmy and others said a bit more control would be nice. The ability to whitelist parts of a blacklisted site (particular pages for eg.) and the ability to allow particular scripts within them would be nice.

I never saw an answer about the dropped URLs. I'm using 1.9.1 and the URLs disappear when I restart the browser and I have to re-enter them all again. I can't be the only one.

A thousand stars.

This add-on gives Firefox functionality that should already be built-in.

A site was giving me a migraine. I installed YesScript and the pain was instantly history.
