Firefox No Script



Firefox

Firefox Extensions: Noscript, Adblock, Adblock Plus Questions - posted in Web Browsing/Email and Other Internet Applications: Im planning on starting to use some basic Firefox security extensions. Download Mozilla Firefox, a free web browser. Firefox is created by a global not-for-profit dedicated to putting individuals in control online. Get Firefox for Windows, macOS, Linux, Android and iOS today!

NoScript is Free Software (source code): if you like it, you can support its progress :)

NoScript 10 'Quantum' resources

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 also provides the most powerful anti-XSS and anti-Clickjacking protection ever available in a browser.

NoScript's unique whitelist based pre-emptive script blocking approach prevents exploitation of security vulnerabilities (known, such as Meltdown or Spectre, 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!

Recommended: protect your Internet traffic, too, with Military Grade Encryption.

V. 11.2.4 - Quantum Security for everyone!

Experts do agree...

03/10/2014, Edward Snowden endorses NoScript as a countermeasure against state Surveillance State.

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!
