Regex-based static network filters are those most likely to cause performance degradation, and as such the best guard against undue performance degradation caused by regex-based filters is the ability to extract valid and good tokens from regex patterns. This commit introduces a complete regex parser so that the static network filtering engine can now safely extract tokens regardless of the complexity of the regex pattern. The regex parser is a library imported from: https://github.com/foo123/RegexAnalyzer The syntax highlighter adds an underline to regex-based filters as a visual aid to filter authors so as to avoid mistakenly creating regex-based filters. This commit further colors the underline as a warning when a regex-based filter is found to be untokenizable. Filter list authors are invited to spot these untokenizable regex-based filters in their lists to verify that no mistake were made for those filters, causing them to be untokenizabke. For example, what appears to be a mistake: /^https?:\/\/.*\/sw.js?.[a-zA-Z0-9%]{50,}/ Though the mistake is minor, the regex-based filter above is untokenizable as a result, and become tokenizable when the `.` is properly escaped: /^https?:\/\/.*\/sw\.js?.[a-zA-Z0-9%]{50,}/ Filter list authors can use this search expression in the asset viewer to find instances of regex-based filters: /^(@@)?\/[^\n]+\/(\$|$)/ |

uBlock Origin
pronounced you-block origin (/ˈjuːˌblɒk/
) — you decide what enters your browser.
English,
Chinese (中文),
Korean (한국어),
Português (Brasil)
BEWARE! uBlock Origin is (and has always been) COMPLETELY UNRELATED to the web site ublock.org
.
An efficient blocker add-on for various browsers. Fast, potent, and lean.
uBlock Origin is NOT an "ad blocker": it is a wide-spectrum blocker -- which happens to be able to function as a mere "ad blocker". The default behavior of uBlock Origin when newly installed is to block ads, trackers and malware sites -- through EasyList, EasyPrivacy, Peter Lowe’s ad/tracking/malware servers, Online Malicious URL Blocklist, and uBlock Origin's own filter lists.

Philosophy
uBlock Origin (or uBlock₀) is not an ad blocker; it's a 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 work with custom rules and filters. Furthermore, advanced mode allows uBlock Origin to work in default-deny mode, which mode will cause all 3rd-party network requests to be blocked by default, unless allowed by the user.
That said, it's important to note 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 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. uBlock Origin'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 uMatrix).
EasyList, EasyPrivacy, Peter Lowe's, Online Malicious URL Blocklist and uBO's own lists are enabled by default when you install uBlock Origin. Many more lists are readily available to block trackers, analytics, and more. Hosts files are also supported.
Once you install uBlock Origin, you may easily un-select any of the pre-selected filter lists if you think uBlock Origin blocks too much. For reference, Adblock Plus installs with only EasyList enabled by default.
Installation
Feel free to read about the extension's required permissions.
Chromium
You can install the latest version manually, from the Chrome Web Store, or from the Opera add-ons.
There is also a development version in the Chrome Web Store if you want to test uBlock Origin with the latest changes: see uBlock Origin dev build.
It is expected that uBlock Origin is compatible with any Chromium-based browsers.
Firefox / Firefox for Android
There is also a development version if you want to test uBlock Origin with the latest changes: for installation, see Install / Firefox webext / For beta version
uBlock Origin is compatible with SeaMonkey, Pale Moon, and possibly other browsers based on Firefox: for installation, see Install / Firefox legacy.
uBO may also be installed as a Debian package:
- Firefox 56-:
apt-get install xul-ext-ublock-origin
- Firefox 55+:
apt-get install webext-ublock-origin
There is no guarantee the package will be available on your specific platform -- in which case, you will have to install from Firefox Add-ons web site.
Microsoft Edge
Publisher: Nik Rolls.
Chromium-based Edge: Stable version available in Microsoft Edge Add-ons.
Safari (macOS)
Developer: @el1t.
Development version available at https://github.com/el1t/uBlock-Safari#ublock-originfor-safari.
Warning: It is not possible for extensions like uBlock Origin to work with Safari 13+. See https://github.com/el1t/uBlock-Safari/issues/158.
Note that issues specific to the Safari fork are the responsibility of the current maintainer, I have no control over the code base of the fork.
Note for all browsers
To benefit from uBlock Origin's higher efficiency, it's advised that you don't use other content blockers at the same time (such as Adblock Plus, AdBlock). uBlock Origin will do as well or better than most popular ad blockers. Other blockers can also prevent uBlock Origin's privacy or anti-blocker-defusing features from working properly.

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 translate uBlock Origin on Crowdin.
