From the project README

An excerpt from the repository, fetched Nov 12, 2026.

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.

It should be true, but the reality is that most ad blockers have such a complex ruleset to match that they can actually go slower and use more RAM than not running them. The graphs that uBlock shows are very compelling: https://github.com/chrisaljoudi/uBlock I'm not saying that Apple tried hard enough; the content blockers on iOS are JIT-compiled to native ARM 64-bit code, so maybe they didn't have the codepath ready for 32-bit and/or they didn't bother. But it's surely not just a technical excuse.
In Crystal – iOS 9 ad blocker
uBlock Origin does a more thorough job at blocking network connections [1] compared to uBlock since the former disables prefetching and the latter doesn't. [2] uBlock is also missing the per-site switches and strict domain blocking features from Origin. [3] Personally I can't see any reason to use uBlock over uBlock Origin.

> looks an awful lot like bad-mouthed rumours Really? So if we look at the Git repo commit history, we'll see the transition commit on April 1st (https://github.com/chrisaljoudi/uBlock/commit/bc4b7fc4ea17c8...). I'm pretty sure we can consider his first commit as demonstrating his intentions if it departs significantly from previous project direction. And it does - the very first commit after the transition was to start soliciting donations (https://github.com/chrisaljoudi/uBlock/commit/f256801344a517...). Git repositories have some reviewable history to them, but I guess that's all just rumours, right? > Seeking for donations is especially a good idea since the original developer left the project because it was too much work -> counteract that work with money. Perhaps. But in that same flurry of commits on his first day of project owners

hip, he linked to a personal donation account (https://github.com/chrisaljoudi/uBlock/commit/31a4a522814f06...). All that's said on that page (https://gratipay.com/~chrisaljoudi/) is that he works on uBlock. Part of the drama was that it previously implied more than just working on it - it was his. His wording has since given more recognition to the contributions of others, thankfully. But Day 1 - he's looking for donations, and its his project. Perhaps not terrible on any other day. But taking an open and free project, slapping personal donation buttons all over it, and removing attribution from other developers by manually committing changes (https://news.ycombinator.com/item?id=9449876) - this behavior turned a lot of people off to his project and leadership. He's since talked about sharing those donations, which I think is good. I still think it would be better to not solicit them, but I don't personally value his contributions that highly any more. That's probably my own bias. > https://github.com/chrisaljoudi/uBlock mentions gorhill and ublock origin in a positive way Those changes are more recent, and came after a lot of public criticism. We can see from the commits that those came in a month and a half after the transition (https://github.com/chrisaljoudi/uBlock/commit/823778274bfd47...). Roughly 2-3 weeks after the video you linked. His first approach was publicity, and then he took a less aggressive approach. Let's not whitewash things when commit history shows that it's only 19 commits back (three of those from other people) from the current mainline on Jun 7th. Normal procedure when taking over project maintainership is to maintain - not reinvent the image for donations. I personally think he saw the opportunity to get some cash for not a whole lot of work, which is a really attractive offer as a high school student. I don't think it was malicious, but I also don't think it was appropriate behavior to take something that was created for free to help others and personally monetize it the moment you got some authority over it. He found out that these things are considered unethical and changed. That's good - and we don't have to lynch him. High school kids do dumber things, and there's still room to learn and grow. But they're not rumours - these things actually happened. There's a reason people prefer the the gorhill fork. I don't think Ajouldi's a bad kid, but I don't fault people for not trusting him after his very public missteps. I think he'll do much better things in the future - and I think part of that is him directly experiencing the fallout of a poor decision before he's gotten a career that could be affected by it. I won't crucify him, but I won't pretend he never did anything wrong just because he apologized.
In UBlock Origin
Sorry, but that looks an awful lot like bad-mouthed rumours I don't like at all. https://github.com/chrisaljoudi/uBlock mentions gorhill and ublock origin in a positive way and asking for donations is totally fine - it would've been a bit strange if that was the first thing he did after getting the project, in an extensive way, but I did not see that while using the extension. Can't have been too bad. Seeking for donations is especially a good idea since the original developer left the project because it was too much work -> counteract that work with money. And I saw the offers to give back the project, which does not fit at all to the negative image projected here. The donations sought are maybe a bit high (which only harms him, since less people might donate), and the one thing that I also don't like. But even that is nothing really bad

, setting the current author is what needed to be done, and finding a proper representation of the original author could be in another commit. There were big expectations that ublock would be totally great, than gorhill left and the new developer (who acted not in a good way to prevent that) got the fallout of the betrayed expectations. And how gorhill acted did not help at all.
