JavaScript Switch ON|OFF is an addon that helps you quickly turn the JavaScript engine in your browser ON or OFF via the toolbar button.
When the toolbar icon color is green, JavaScript is allowed in the browser, and when it turns red, it means JavaScript is denied globally. Now you can reload any website without JavaScript running. If you need to whitelist a domain (i.e. www.example.com) please right-click on any page and then click on the - Add domain to the whitelist - context menu item. Alternatively, you can open the options page and add the desired domain to the designated area (text area). Please note, domains need to be added comma-separated (domain1.com, domain2.com, etc). You can also enter URLs and the addon will convert them to a domain.
To report bugs, please fill the bug report form on the addon's homepage (https://mybrowseraddon.com/javascript-switch.html).
