Stay safe by avoiding malicious scripts online

NoScript is a security add-on for Firefox that aims to prevent auto-executing plugins that could put you at risk of malicious scripts, clickjacking and attacks.

NoScript works by automatically preventing scripts from executing on the websites you visit. If you click on the little NoScript icon in the lower right corner, you’ll be able to see what scripts are being prevented and decide which you want to allow and which you want to exclude for security reasons.

The culprits that NoScript avoids are JavaScript, Java and Flash and other plugins. If you know a site to be safe, you can allow the scripts, either temporarily or globally. You can also permit just some of the scripts that are in place, or you can allow everything on a given page, rather than a whole site.

The NoScript configuration options are extensive and to get the most out of it, you’ll need to put some effort in. Even so, there is plenty of help available on the developer’s website and around the web. You can add safe websites to the NoScript whitelist, configure what appears in the context menu, as well as specifying more technical details.

If this is too much for you, however, don’t worry. Using NoScript is actually very easy – allow the add-on to block what it deems appropriate and only unblock if you really trust the website you’re visiting.

NoScript – staying safe online couldn’t be easier.

    Extra Security Protection For Firefox. NoScript is a very powerful add-on for Firefox that adds extra protection by disabling Javascript on certain sites. By default it partially blocks all sites except on the default whitelist. It's pretty simple to use but can be time consuming and will slow down your surfing. If you wish for a site to be fully allowed or disabled just right click on the add-on and choose your preference. This should be used with caution and most of the time the default is fine for most and only add sites you use that need full javascript access to function.The downsides are the fact it is time consuming to set up for maximum protection. It will slow down you surfing. Certain sites will not work unless they have full access and every time you install NoScript you have to do all the customization all over again.All in all I don't recommend NoScript for most. Most will get annoyed with how slow it make Firefox and how much effort it takes to make their favorite sites work the way they want it while blocking everything else. Pros: Adds Extra ProtectionSimple Click and Choose OptionsFree Cons: Will Slow Down SurfingCan Cause Users To Become ParanoidA Lot Of Users Will Get Annoyed By The Time It Takes To Customize It
