uBlock Origin is honestly a must have. With this CPU friendly extension, you can block ads and trackers easily! It has an intuitive and clean simplified UI on clicking the extension icon, which shows everything you need to know. This extension also comes with a feature allowing you to hide elements you don't want just by pressing the eye dropper icon and selecting on that element, allowing you to keep whatever environment you use this on, distraction free. In addition, you can also add more "filters" which in the extension settings, you can block things like for example, anything Facebook related etc. which is great!

The best part about all of this is you don't need to be smart to use this, it has all the basic features set-up by default, so you really don't need to configure anything.

The only small problem, which isn't really a problem but could be improved is how the settings UI is all crammed onto the left. It just doesn't really have a design that is consistent as the extensions menu UI, but don't let this stop you from installing this extension because it doesn't have any true downsides!
