A recent update to the cross-browser content blocker uBlock Origin introduced an option to block JavaScript by default for all visited sites or individual sites.

The new option of uBlock Origin 1.17.0 gives users even better control when it comes to blocking content from running automatically on sites that they visit in any of the supported browsers.
Side note: you can read my journey to getting uBlock Origin to update to the new version in Chrome here.
The first thing that you need to do is make sure that you run at least uBlock Origin 1.17.0. Click on the extension's icon in the address bar of the browser that you are using and in the interface that opens on the settings icon. Switch to the about tab on the dashboard; the version of the extension is listed there.
