Once 1Blocker is installed, it's worth configuring its core features, and this article explains how to do it.

Also, before proceeding to these steps, we’d recommend checking out the following article to get better acquainted with the tools we use: How 1Blocker protects you

Enable content blocking in Safari

iOS:

Go to iOS Settings > Safari > Extensions (under "General").

There will be eight 1Blocker switches that correspond to specific blocking categories of the app. We recommend enabling all of them in your device's Settings and managing specific categories in the 1Blocker app.

macOS:

In the Safari browser, go to Safari > Preferences > Extensions to turn on 1Blocker extensions.

Now it's worth checking whether these categories are enabled in the app itself.

You just need to open the 1Blocker app and turn on the content blocking categories you are interested in. Most of them are in the General tab of the app, but you might also want to enable a couple of regional categories as well.

The setup could be the following: Block Ads on Sites + Block Web Trackers + Block Annoyances + Block Widgets.

Important: the free version of 1Blocker allows using one blocking category at the same time, while multiple blocking categories require 1Blocker Premium.
