This wikiHow teaches you how to turn off your web browser's JavaScript support. JavaScript is responsible for loading dynamic content in webpages, so turning it off can help websites load faster than usual. Most web browsers and their mobile counterparts allow you to disable JavaScript from within the browser's settings; however, you can't disable JavaScript in the iPhone version of both the Google Chrome app and the Firefox app, and Microsoft Edge doesn't include an option to disable JavaScript.
