## Philosophy
|
|
|
|
µBlock is not an *ad blocker*; it's a general-purpose blocker. µBlock blocks ads through its support of the [Adblock Plus filter syntax](https://adblockplus.org/en/filters). µBlock [extends](https://github.com/gorhill/uBlock/wiki/Filter-syntax-extensions) the syntax and is designed to work with custom rules and filters.
|
|
|
|
That said, it's important to note that using a blocker is **NOT** [theft](https://twitter.com/LeaVerou/status/518154828166725632). 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. **µBlock'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](https://github.com/gorhill/uMatrix)).
|
|
|
|
_EasyList_, _Peter Lowe's Adservers_, _EasyPrivacy_ are enabled by default when you install µBlock. Many more lists are readily available to block trackers, analytics, and more. Hosts files are also supported.
|
|
|
|
## Performance

|
|
#### Memory

|
|
|
|
<sup>**Important note regarding memory usage:** There is currently a [bug in Chromium 39+ which causes a new memory leak each time the popup UI of an extension is opened](https://code.google.com/p/chromium/issues/detail?id=441500). This affects *all* extensions. Keep this in mind when measuring Chromium's memory usage. In the benchmarks, I avoided opening the popups completely.</sup>
|
|
|
|
#### CPU
|
|
|
|
<p align="center">
|
|
µBlock is also easy on the CPU<br>

|
|
|
|
#### Blocking
|
|
|
|

|
|
Being lean and efficient doesn't mean blocking less<br>

## Installation
|
|
|
|
Feel free to read [about the extension's required permissions](https://github.com/gorhill/uBlock/wiki/About-the-required-permissions).
|
|
|
|
#### Chromium
|
|
|
|
You can install the latest version [manually](https://github.com/gorhill/uBlock/tree/master/dist#install), from the [Chrome Web Store](https://chrome.google.com/webstore/detail/cjpalhdlnbpafiamejdnhcphjbkeiagm), or from the [Opera store](https://addons.opera.com/en-gb/extensions/details/ublock/).
|
|
|
|
#### Firefox
|
|
|
|
You can install by downloading the latest [uBlock.firefox.xpi](https://github.com/gorhill/uBlock/releases) file, and by dragging the downloaded `xpi` file to your add-on page.
|
|
|
|
#### Safari
|
|
|
|
You can get µBlock for Safari (Yosemite's 8.0 or newer) from the [Safari Extension Gallery](https://extensions.apple.com/details/?id=net.gorhill.uBlock-96G4BAKDQ9).
|
|
|
|
<sup>There are currently no plans to support older Safari's. It's not recommended that you install µBlock on them (*do it at your own risk*).</sup>
|
|
|
|
#### Note for all browsers
|
|
|
|
To benefit from µBlock's higher efficiency, it's advised that you don't use other inefficient blockers at the same time (such as AdBlock or Adblock Plus). µBlock will do [as well or better](#blocking) than most popular ad blockers.
|
|
|
|
## Release History
|
|
|
|
See the [releases pages](https://github.com/gorhill/uBlock/releases) for a history of releases and highlights for each release.
|
|
|
|
## Documentation
|
|
|
|
µBlock's functionality is self-explanatory and intuitive for the most part. One thing to note after you get started is the big power button in µBlock's popup:
|
|
|
|
|
|
|
|
The big power button is to disable/enable µBlock for the specific current site/hostname (as extracted from the URL of the current page).
|
|
|
|
**In other words, it applies to the current site only; it is *not* a global power button.** The state of the power switch for a specific site will be remembered.
|
|
|
|
For advanced usage, read about [dynamic filtering](https://github.com/gorhill/uBlock/wiki/Dynamic-filtering:-quick-guide) and more on [µBlock's wiki](https://github.com/gorhill/uBlock/wiki).

## About
|
|
|
|
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.
|
|
|
|
You can contribute by helping to translate this project. There's an
|
|
[entry on Crowdin](https://crowdin.net/project/ublock) where you may contribute to µBlock's localization.
