uBlock: an efficient blocker add-on for various browsers. Fast, potent, and lean.

Build status Support Development

What is uBlock?

uBlock is a general-purpose blocker — not an ad blocker specifically.

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.

uBlock's main goal is to help users neutralize privacy-invading apparatus — ads being one example.

Getting started

Quick guide for basic usage.

Installation:

Performance

Memory

On average, uBlock really does make your browser run leaner. [1]

Chromium [2]


Firefox


Safari


[1] Details of the benchmark available at Firefox version: benchmarking memory footprint.

[2] Important note: There is currently a bug in Chromium 39+ which causes a new memory leak each time the popup UI of an extension is opened. This affects all extensions. Keep this in mind when measuring Chromium's memory usage. In the benchmarks, I avoided opening the popups completely.

CPU

uBlock is also easy on the CPU

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.

Quick tests

Release History

See the releases pages for a history of releases and highlights for each release.

Tips

  • To benefit from uBlock's higher efficiency, it's advised that you don't use other inefficient 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, Peter Lowe's Adservers, EasyPrivacy and Malware domains 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's manifesto.

Free. Open source. For users by users.

If uBlock is useful to you, donations to support development are much appreciated.

uBlock is made useful because of the filter lists it utilizes. We deeply appreciate the people working hard to maintain the filter lists we're using, which were made available to use by all for free.
