Want a quick and easy way to toggle JavaScript on and off in Firefox? Then you will definitely want to take a good look at the JS Switch extension.


There are three ways to set up access to JS Switch. The first is through the “Customise Toolbar Window”.

To activate the other two you will need to open the “Options Window” and select the method that you prefer best.

If you activate the “Tools Menu” option, there will be a singular entry that will have a check mark beside it when JavaScript is enabled.

The “Status Bar Button” will display in a red color when JavaScript is enabled and in a light gray color when it is not.

JS Switch in Action


For our example we chose to use the “Toolbar Button”. As you can see JavaScript is enabled (red color). To deactivate JavaScript in your browser simply click on the button.

If you already have a webpage loaded like in our example, you just need to refresh that particular page. Until you re-enable JavaScript all webpages that you browse will have their JavaScript disabled. Notice the gray color of the “Toolbar Button”…

Depending on how heavily a particular website uses JavaScript you can expect to see varying results in how the pages look. In our example you can see that AirSet depends heavily on JavaScript and the webpage is practically non-functional.


If you are looking for a quick “no questions asked” method for enabling/disabling JavaScript in Firefox, then this extension will make a nice addition to your browser.
