uBlock Origin is lightweight, effective, and free from shady business practices. Unfortunately, Google's move to Manifest V3 for browser extensions has hobbled ad blockers somewhat. In response, uBlock has split into two products—uBlock Origin and uBlock Origin Lite. The "Lite" version works with most Chromium-based browsers and Safari for iPhone, iPad, and Mac. The full version of uBlock Origin primarily works in Firefox for desktops, laptops, and Android. With those differences highlighted, here are the 10 uBlock Origin (and uBlock Origin Lite) hacks you should know about.

Use the element zapper to remove distracting elements

icon to disable JavaScript on the webpage. Reload the page, and Firefox will load it without JavaScript.
Try these shortcuts to disable uBlock Origin on a single page in Firefox
uBlock Origin for Firefox lets you block large media elements on all sites (or single pages). This allows you to reduce data usage on a metered connection. You can use it to block media elements above a custom size threshold like 10KB, 20KB, etc. To try this on a single webpage, click uBlock Origin's toolbar icon, and then click the film reel icon. Reload the page, and you'll notice that certain elements won't load. To set a custom size threshold for these elements, go to uBlock Origin settings in Firefox.

In Firefox, you can go to uBlock Origin settings, and turn on Enable cloud storage support. Your uBlock Origin settings will then sync to every device where you're logged in with the same Firefox account.
Use uBlock Origin's tracking link blocker to stop sites from tracking your clicks
Many websites add trackers to links you copy. Sites like Instagram, Facebook, and Threads use sharing links to trace which profile shared the links with you. Luckily, uBlock Origin can block most of these types of trackers. In uBlock Origin settings, go to Filter lists, and enable AdGuard/uBO — URL Tracking Protection. That said, I recommend that you check the URLs before sharing them with others. Sometimes, you may have to manually strip tracking data because no anti-tracking feature is completely foolproof.
Reduce tracking on international websites with region-specific blocklists
uBlock Origin also ships with region-specific blocklists that target trackers from different locations across the world. If you find yourself accessing many websites from foreign countries, you should enable these blockers from uBlock Origin's settings. In the Filter lists tab, click the Regions, languages button to expand the list. This will reveal all country or region-specific blocklists. Enable the ones you need, and you're all set.
