NoScript also provides the most powerful anti-XSS and anti-Clickjacking protection ever available in a browser.The NoScript Firefox extension provides extra protection for Firefox, Seamonkey and other mozilla-based browsers: this free, open source add-on allows JavaScript, Java, Flash and other plugins to be executed only by trusted web sites of your choice (e.g. your online bank).

NoScript’s unique whitelist based pre-emptive script blocking approach prevents exploitation of security vulnerabilities (known and even not known yet!) with no loss of functionality…

You can enable JavaScript, Java and plugin execution for sites you trust with a simple left-click on the NoScript status bar icon (look at the picture), or using the contextual menu, for easier operation in popup statusbar-less windows.
Watch the “Block scripts in Firefox” video by cnet.

Staying safe has never been so easy!
Experts will agree: Firefox is really safer with NoScript!

V. 2.6.5.7 – Friendly Security

If you find any bug or you’d like an enhancement, before reporting here or here, please check if it’s fixed in latest development build. Many thanks!

Main good news
  • Several XSS filter enhancements, thanks to Masato Kinugawa’s research.
  • New “Security Downgrade Warning” suggests blacklist mode as a better option than uninstalling, in order to retain scripting-unrelated protections.
  • Improved Google Analytics Surrogate, makes more sites work correctly with google-analytics.com blocked.
  • ClearClick accuracy improvements.
  • Added navigator.doNotTrack property support.
  • Added new fake mimetype placeholder “FRAME” to match FRAMEs and IFRAMES with the noscript.allowedMimeRegExp preference
  • for selecting blocking exceptions.

  • Holding the left mouse button down on an absolutely positioned page element and hitting the DEL key will remove it if scripts are disabled (useful to forcibly kill in-page popups). This feature can be disabled by setting the noscript.eraseFloatingElements about:config preference to false.
  • Right-clicking on NoScript menu items copy site domains to the clipboard (useful for reporting and investigating sites, thanks Tom T. for RFE)
  • Browserid.org has been added to the default whitelist.
  • “Click to play” protection against WebGL exploitation, now also on whitelisted sites (can be enabled in NoScript Options|Embeddings)
  • Security and Privacy Info page is shown whenever you middle-click on sites exposed by NoScript’s UI, either in the menus or in the Whitelist options tab.
  • Middle clicking NoScript’s toolbar button temporarily allows all on current page.

changelog

Experts do agree…

08/06/2008, “I’d love to see it in there.” (Window Snyder, “Chief Security Something-or-Other” at Mozilla Corp., interviewed by ZDNet about “adding NoScript functionality into the core browser”).

03/18/2008, “Consider switching to the Firefox Web browser with the NoScript plug-in. NoScript selectively, and non-intrusively, blocks all scripts, plug-ins, and other code on Web pages that could be used to attack your system during visits” (Rich Mogull on TidBITS, Should Mac Users Run Antivirus Software?).

11/06/2007, Douglas Crockford, world-famous JavaScript advocate and developer of JSON (one of the building blocks of Web 2.0), recommends using NoScript.

03/16/2007, SANS Internet Storm Center, the authoritative source of computer security related wisdom, runs a front-page Ongoing interest in Javascript issues diary entry by William Stearns just to say “Please, use NoScript” 🙂
Actually, NoScript has been recommended several times by SANS, but it’s nice to see it mentioned in a dedicated issue, rather than as a work-around for specific exploits in the wild. Many thanks, SANS!

05/31/2006, PC World’s The 100 Best Products of the Year list features NoScript at #52!

Many thanks to PC World, of course, for grokking NoScript so much, and to IceDogg who kindly reported these news…

In the press…

  • Forbes: “The real key to defeating malware isn’t antivirus but approaches like Firefox’s NoScript plug-in, which blocks Web pages from running potentially malicious programs” (Dec 11, 2008, Andy Greenberg, Filter The Virus Filters).
  • PC World: Internet Explorer 7 Still Not Safe Enough because it doesn’t act like “NoScript […] an elegant solution to the problem of malicious scripting” (cite bite)
  • New York Times: “[…] NoScript, a plug-in utility, can limit the ability of remote programs to run potentially damaging programs on your PC”, (Jan 7, 2007, John Markoff, Tips for Protecting the Home Computer).
  • PC World’s Ten Steps Security features using NoScript as step #6. (cite bite)
  • The Washington Post security blog compares MSIE “advanced” security features (like so called “Zones”) to Firefox ones and recommends NoScript adoption as the safest and most usable approach. (cite bite)
