Disabling JavaScript can improve browser speed and performance. Opera users who wish to disable JavaScript can do so in a few easy steps. This tutorial applies to Opera version 63 on macOS. The steps are virtually the same for Opera in Windows, macOS, and older Mac operating systems. How to Disable JavaScript in Opera Follow these steps: Select Opera from the menu bar, then select Preferences. The Opera Settings interface displays in a new tab. In the left menu pane, select Advanced. Select Site Settings. Select JavaScript. Slide the Allowed toggle switch to the left. The toggle button turns gray, and JavaScript is blocked on all pages. In addition to this all-or-nothing approach, Opera allows you to specify whether to allow JavaScript on specific web pages, entire sites, or domains. These lists are handled in the Block and Allow sections, located below the aforementioned toggles. Select Add to add a site to the Block or Allow list. Was this page helpful?
