Philosophy

uBlock Origin (or uBlock₀) is not an ad blocker; it'due south a full general-purpose blocker. uBlock Origin blocks ads through its support of the Adblock Plus filter syntax. uBlock Origin extends the syntax and is designed to piece of work with custom rules and filters. Furthermore, advanced mode allows uBlock Origin to work in default-deny mode, which mode will cause all 3rd-political party network requests to be blocked past default, unless allowed by the user.

That said, it'south important to annotation 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 correct to privacy.

Ads, "unintrusive" or not, are just the visible portions of privacy-invading appliance entering your browser when yous visit most sites nowadays. uBlock Origin's main goal is to assistance users neutralize such privacy-invading apparatus — in a way that welcomes those users who don't wish to utilize more technical, involved means (such as uMatrix).

EasyList, EasyPrivacy, Peter Lowe's, Online Malicious URL Blocklist and uBO'due south own lists are enabled by default when y'all install uBlock Origin. Many more lists are readily bachelor to block trackers, analytics, and more. Hosts files are too supported.

Once you install uBlock Origin, yous may easily un-select any of the pre-selected filter lists if you call back uBlock Origin blocks likewise much. For reference, Adblock Plus installs with only EasyList, ABP filters and Adequate Ads enabled by default.
