Disable/Enable Javascript Options in Firefox From Version 23.

By | August 31, 2013

Folks,

You might have noticed, In Firefox Version 23(+) there is no way to disable  JavaScript functionality from Tools->options-> Content (Tab). They say “In Firefox 23, as part of an effort to simplify the Firefox options set and protect users from unintentionally damaging their Firefox, the option to disable JavaScript was removed from the Firefox Options window.”

The option to disable JavaScript was not removed from Firefox entirely. You can still access it from about:config or by installing an add-on.

How to disable (& enable back) Javascript from Firefox ver. 23

about:config

  1. In the address bar, type “about:config” (with no quotes), and press Enter.
  2. Click “I’ll be careful, I promise”
  3. In the search bar, search for “javascript.enabled” (with no quotes).
  4. Right click the result named “javascript.enabled” and click “Toggle”. JavaScript is now disabled.


To Enable JavaScript back, repeat these steps.

Add-ons

You can alternatively install an add-on that lets you disable JavaScript, such as

  • No-Script (to disable JavaScript on a per page basis, as required)
  • QuickJava (to easily disable and enable JavaScript, automatic loading of images, and other content)

Hope this helps. ThankYou.

Cheers,

JENSon.
