uBlock Origin

An efficient blocker: easy on memory and CPU footprint, and yet can load and enforce thousands more filters than other popular blockers out there.

Illustrated overview of its efficiency: https://github.com/gorhill/uBlock/wiki/uBlock-vs.-ABP:-efficiency-compared

Usage: The big power button in the popup is to permanently disable/enable uBlock for the current web site. It applies to the current web site only, it is not a global power button.

***

Flexible, it's more than an "ad blocker": it can also read and create filters from hosts files.

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

- EasyList
- Peter Lowe’s Ad server list
- EasyPrivacy
- Malware domains

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

- Fanboy’s Enhanced Tracking List
- Dan Pollock’s hosts file
- hpHosts’s Ad and tracking servers
- MVPS HOSTS
- Spam404
- And many others

Of course, the more filters enabled, the higher the memory footprint. Yet, even after adding Fanboy's two extra lists, hpHosts’s Ad and tracking servers, uBlock still has a lower memory footprint than other very popular blockers out there.

Also, be aware that selecting some of these extra lists may lead to higher likelihood of web site breakage -- especially those lists which are normally used as hosts file.

***

Without the preset lists of filters, this extension is nothing. So 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.

uBlock is perfect but dont need to install as a add-on, you can add any list of uBlock in embedded opera add-on extension, its much more faster and better expressions, and please mind opera block in trafic level but other add-on just remove the element after DOM ready!

if only to block ads UBLOCK ORIGIN is useless it includes this not one blocked popup
because opera already has its own adblock

This app was the only blocker that ran under the radar at all PCH websites, (LOVED IT!!) but alas, as of 4/1/2019 they have stepped up their game and UBlock no longer goes undetected, You can still toggle on and off to get things to load, but its a hassle. Can someone work on a filter for PCH.com as, all of their sites use the same basic format, for the ad player which now has to load in between EACH game played. Or you can load it with uBlock paused, then quickly toggle back on to bypass the ad player. Thanks! You STILL ROCK though, just sayin!
