Now Block JavaScript for Specific Sites in Chrome 75 Beta on Android

Like most web browsers, users can disable javascript in the desktop version of Google Chrome. Chrome for Android also offers the option to completely disable javascript for all sites. Though one can whitelist a site by adding it as an exception to prevent its javascript from being blocked. However, it’s highly unlikely that you may want to turn off javascript for all the websites. I would rather prefer to keep javascript enabled by default and disable it only for certain sites. Thankfully, Chrome 75 Beta has added the functionality to directly block javascript for a specific site.

By blocking javascript you can peacefully access a particular site plagued with numerous ads and spammy redirects. Besides annoying ads, you can get rid of pesky pop-ups and paywall that force you to subscribe to access the site’s content. Moreover, blocking unwanted scripts from loading up can relatively boost the load time of a webpage. Having said that, it is important to note that disabling javascript can break certain elements and can even make some websites unusable. In such a case, you can simply allow javascript for a site whenever you like.
