How To Enable or Disable JavaScript In Chrome, Firefox, Safari, etc.

JavaScript is enabled by default in all web browsers such as Chrome, Firefox, Safari, IE and Opera. But the browser companies do allow users to enable or disable JavaScript from settings, so the websites we visit will not able to execute client-side scripts. You can disable JavaScript in mobile browsers too.

If you disable JS, many popular websites will no more work correctly in that browser. If you have any problem with a specific website, you can disable JavaScript only for that specific website, rather than all websites. If you have problems with the website ads, try Adblock plus browser extension and automatically block ads from all websites you visit.
