Enable – Disable javascript in Mozilla Firefox version 23+

You might be wondering that where the hell did the “disable javascript” option go from the Firefox Option window. The thing is that, now a days, software vendors are trying to make simplify their products and making them robust by protecting users form accidentally damaging the piece of software, in this case Mozilla Firefox. Following this trend, the disable JavaScript option was removed from the Firefox Options since the version 23.

But there is nothing for you to worry about, because the disable javascript option is not completely removed from Firefox, just the way to reach option is changed. There are still 2  ways to reach that setting, i.e

1. about:config

  1. Open firefox and type “about:config” ( without quotes ) and press Enter.
  2. You will see a notice “This might void your warranty!”. Click “I’ll be careful, I promise”.
  3. Search for “javascript.enabled” ( without quotes ) in the search bar at top of the page.
  4. Double click the result name “javascript.enabled” or Right click it and select “Toggle”.
  5. Hurrey!!!! Javascript is now disabled on your browser.

If you want to Re-enable javascript, repeat these steps.

2. Add-ons

There are few add-ons also available for Firefox which you can use as an alternative to the manual method ( about:config ).

  1. No-Script ( A plugin to disable JavaScript on a per page basis, as required.)
  2. QuickJava ( A plugin to easily disable and enable JavaScript.)
