To enable or disable JavaScript in Mozilla Firefox:

1. Open Firefox and click on the three horizontal lines (Menu button) in the top right corner of the window.
2. Select Options from the menu.
3. Scroll down to the section labeled Content Blocking.
4. Click on the adjacent Settings button.
5. Under the section labeled Custom, click on the toggle switch next to JavaScript to disable it.
6. If you want to enable JavaScript again, just toggle the switch back to its original position.

Alternatively, you can enable or disable JavaScript by typing "about:config" in the address bar and pressing Enter. Search for "javascript.enabled" in the search bar and toggle the value to true (to enable) or false (to disable).
