Javascript nasty

Last updated on June 24th, 2015 at 01:34 am

Today I also came across a nasty endless loop Javascript. This sucker can trap IE, Firefox and Opera in an endless loop requiring you to kill the application via task manager or kill the process if using one of the *nix.

Go get the NoScript – Firefox Extension immediately.

From the description

NoScript allows JavaScript execution only for trusted domains of your choice (e.g. your home-banking web site). This whitelist based pre-emptive script blocking approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality? Experts will agree: Firefox is really safer with NoScript ;-)

If you doubt the need for this I point you to the following site. I won?t link to it as it will kill 90% of my visitors? browsers. Save your work first and copy the address and paste it into your address bar. It will kick off an endless loop javascript. Let me know if your browser is safe. Of course that applies only if you have javascript on.
