Description

Finally, an efficient blocker. Easy on CPU and memory.

IMPORTANT: uBlock Origin is completely unrelated to the site "ublock.org".

uBlock Origin is not an "ad blocker", it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.

***

Out of the box, these lists of filters are loaded and enforced:

- uBlock Origin filter lists
- EasyList (ads)
- EasyPrivacy (tracking)
- Peter Lowe’s Ad server list (ads and tracking)
- Online Malicious URL Blocklist

More lists are available for you to select if you wish:

- Annoyances (cookie warnings, overlays, etc.)
- hosts-based lists
- And many others

Additionally, you can point-and-click to block JavaScript locally or globally, create your own global or local rules to override entries from filter lists, and many more advanced features.

***

Free.

For users by users.

If ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.

Absolutely fantastic add-on for those who is annoyed by ANY kind of ads whether that be YouTube ads, heck even Spotify ads are blocked by this adblocker! Now I can finally browse the web without having to worry about trojans from virus-filled ads getting into my computer because thanks to uBlock, they're automatically blocked when they're detected. This is also a great installation to use not just for your personal computer, I know so many schools that use this add-on to protect their students from ads including mine at some point! I 110% recommend uBlock to people who are looking for adblockers that are SURE to do their job! I also recommend using an adblock test (you can easily find a site by searching it up on google, microsoft edge, etc) just to make sure it works. But I assure you, uBlock does its job perfectly! Absolutely wonderful add-on for being free, I will 110% be using this from now on. :)

This works, and it works well. You do need to remember to update your block lists, and it is at times cat and mouse with the BS adds. It is free, though you can support them on their page. It will generally keep you away from the call 1-800-scam me pop ups. I default install this on all systems I maintain. Even the US government suggests that you install add blockers.
