uBlock Origin is NOT an “ad blocker”: it is a wide-spectrum blocker — which happens to be able to function as a mere “ad blocker”. The default behavior of uBlock Origin when newly installed is to block ads, trackers and malware sites — through EasyList, EasyPrivacy, Peter Lowe’s ad/tracking/malware servers, various lists of malware sites, and uBlock Origin’s own filter lists.
uBlock Origin (or uBlock₀) is not an ad blocker; it’s a general-purpose blocker. uBlock₀ blocks ads through its support of the Adblock Plus filter syntax. uBlock₀ extends the syntax and is designed to work with custom rules and filters. Furthermore, advanced mode allows uBlock₀ to work in default-deny mode, which mode will cause all 3rd-party network requests to be blocked by default, unless allowed by the user.
That said, it’s important to note that using a blocker is NOT theft. Don’t fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalisation of the inalienable right to privacy.
Ads, “unintrusive” or not, are just the visible portions of privacy-invading apparatus entering your browser when you visit most sites nowadays. uBlock₀’s main goal is to help users neutralize such privacy-invading apparatus — in a way that welcomes those users who don’t wish to use more technical, involved means (such as µMatrix).
EasyList, Peter Lowe’s Adservers, EasyPrivacy and Malware domains are enabled by default when you install uBlock₀. Many more lists are readily available to block trackers, analytics, and more. Hosts files are also supported.
Once you install uBlock₀, you may easily un-select any of the pre-selected filter lists if you think uBlock₀ blocks too much. For reference, Adblock Plus installs with only EasyList enabled by default.
You can install the latest version manually, from the Chrome Store, or from the Opera store (uBlock Origin is published under the name “µBlock” in the Opera store — the name can’t be changed).
It is expected that uBlock Origin is compatible with any Chromium-based browsers.
Free. Open source. For users by users. No donations sought.
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.
