NoScript
NoScript (or NoScript Security Suite) is a free and open-source extension for Firefox- and Chromium-based web browsers, written and maintained by Giorgio Maone, a software developer and member of the Mozilla Security Group.
By default, NoScript blocks active (executable) web content, which can be wholly or partially unblocked by allowlisting a site or domain from the extension's toolbar menu or by clicking a placeholder icon.
In the default configuration, active content is globally denied, although the user may turn this around and use NoScript to block specific unwanted content. The allowlist may be permanent or temporary (until the browser closes or the user revokes permissions). Active content may consist of JavaScript, web fonts, media codecs, WebGL, Java applet, Silverlight and Flash. The add-on also offers specific countermeasures against security exploits.
Because many web browser attacks require active content that the browser normally runs without question, disabling such content by default and using it only to the degree that it is necessary reduces the chances of vulnerability exploitation. In addition, not loading this content saves significant bandwidth and defeats some forms of web tracking.
NoScript is useful for developers to see how well their site works with JavaScript turned off. It also can remove many irritating web elements, such as in-page pop-up messages and certain paywalls, which require JavaScript in order to function.
NoScript takes the form of a toolbar icon or status bar icon in Firefox. It displays on every website to denote whether NoScript has either blocked, allowed, or partially allowed scripts to run on the web page being viewed. Clicking or hovering (since version 2.0.3rc1) the mouse cursor on the NoScript icon gives the user the option to allow or forbid the script's processing.
NoScript's interface, whether accessed by right-clicking on the web page or the distinctive NoScript box at the bottom of the page (by default), shows the URL of the script(s) that are blocked, but does not provide any sort of reference to look up whether or not a given script is safe to run. With complex webpages, users may be faced with well over a dozen different cryptic URLs and a non-functioning webpage, with only the choice to allow the script, block the script or to allow it temporarily.
On November 14, 2017, Giorgio Maone announced NoScript 10, which will be "very different" from 5.x versions, and will use WebExtension technology, making it compatible with Firefox Quantum. On November 20, 2017, Maone released version 10.1.1 for Firefox 57 and above. NoScript is available for Firefox for Android.
