Read the project’s introduction
Future releases of uBlock will be made available on our website at https://ublock.org uBlock: an efficient blocker extension for your browser. Fast, potent, and lean. Getting Started & Installation Performance & Benchmarks Tips FAQ About Getting started Installation: Chrome: available on the Chrome Web Store or for manual installation. Safari: available to install from the homepage. MacOS App: available for install from the homepage or from the App Store. Firefox: available on the Firefox Add-ons site, or for manual installation. Opera: Opera shares Chrome's underlying engine, so you can install uBlock simply by grabbing the latest release for Chrome. uBlock has tooltips throughout its UI to help you along. But just in case you need it, here's a quick guide for basic usage. Performance Memory On average, uBlock really does make your browser run leaner. [1] Chrome Safari Firefox [1] An overview of the benchmark is available at this wiki page. CPU uBlock is also CPU-efficient Details of the benchmark available in this LibreOffice spreadsheet. Blocking Being lean and efficient doesn't mean blocking less For details of benchmark, see uBlock and others: Blocking ads, trackers, malwares. Some quick tests: These tests are by no means complete or comprehensive, but do remain helpful. Index Web page components Popups Tips To benefit from uBlock's higher efficiency, it's advised that you don't use other blockers at the same time (such as AdBlock or Adblock Plus). uBlock will do as well or better than most popular ad blockers. It's important to note that blocking ads 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. EasyList, Acceptable Ads, ABP Anti-Circumvention Filter List‎ and Cryptocurrency (Bitcoin) Mining Protection List‎ are enabled by default when you install uBlock. Many more lists are readily available to block trackers, analytics, and more. Hosts files are also supported. Once you install uBlock, you can easily un-select any of the pre-selected filter lists if you think uBlock blocks too much. For reference, Adblock Plus installs with only EasyList enabled by default. Feel free to read about the extension's required permissions. About uBlock Some users might want to check out uBlock Origin: a noteworthy personal fork of uBlock from @gorhill with a slightly different featureset. uBlock is a general-purpose content blocker, which means it can be used to block ads as well as other forms of content on webpages. uBlock can also be used to help users neutralize privacy-invading trackers. uBlock blocks ads through its support of the Adblock Plus filter syntax. uBlock extends the syntax and is designed to work with custom rules and filters. ** Please note recent news about the status of the uBlock project as of June 22, 2018.** Acknowledgment: uBlock comes with several filter lists ready to use out-of-the-box (including but not limited to: EasyList, Peter Lowe's, several malware filter lists). We deeply appreciate the people working hard to maintain those lists which are available to use by all for free. License GPLv3.

What Hacker News says

It seems like they are just trying to steal the name of uBlock. AdBlock CEO says they “do love the name” [0] and are "investing heavily" into the product, but the commits in the repo [1] are just cosmetic changes and rebranding. Oddly enough, the only active committer is anonymous. I wonder if this will cause legal troubles to the true uBlock Origin.

In An update on uBlock
https://www.reddit.com/r/ublock/comments/32mos6/ublock_vs_ub... https://github.com/uBlock-LLC/uBlock/issues/1706 Basically what AdBlock bought is the technical right to say "this extension is the original uBlock project" which is a part of narrative on https://www.ublock.org/announcement/ https://chrome.google.com/webstore/detail/ublock/epcnnfbjfcg... but as far as community is concerned it died when it was transferred over and resurrected shortly after under a new repo on Gorhils account
