Related issue: https://github.com/uBlockOrigin/uBOL-home/issues/157 The `header=` option will be converted into DNR's `responseHeaders` condition. There will be an attempt to convert regex-based values into DNR- compatible syntax. Not all regex-based patterns can be converted to use DNR's patterns with `*` and `?` special characters. The implementation of `header=` option in uBO has been revisited to improve compatibility with DNR syntax to minimize burden for list maintainers when creating `header=` filters compatible with both uBO and uBOL. The changes: - Header names are now case-insensitive by default - Occurrences of `*` in non-regex-based header values now mean "matches any number of characters" - Occurrences of `?` in non-regex-based header values now mean "matches zero or one character" At time of commit, and as per MDN, only Chromium-based browsers currently support filtering on repsonse headers: https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/declarativeNetRequest/HeaderInfo Also as per MDN, Chromium 121-127 silently ignore the `responseHeaders` condition, potentially causing undue blocking of network requests. Currently uBOL support Chromium 122 and later, meaning we need to mind potential false positives in Chromium 122-127 for filters using `header=` option. |

uBlock Origin (uBO)
uBlock Origin (uBO) is a CPU and memory-efficient wide-spectrum content blocker for Chromium and Firefox. It blocks ads, trackers, coin miners, popups, annoying anti-blockers, malware sites, etc., by default using EasyList, EasyPrivacy, Peter Lowe's Blocklist, Online Malicious URL Blocklist, and uBO filter lists. There are many other lists available to block even more. Hosts files are also supported. uBO uses the EasyList filter syntax and extends the syntax to work with custom rules and filters.
You may easily unselect any preselected filter lists if you think uBO blocks too much. For reference, Adblock Plus installs with only EasyList, ABP filters, and Acceptable Ads enabled by default.
It is important to note that using a blocker is NOT theft. Do not fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalization of the inalienable right to privacy.
Ads, "unintrusive" or not, are just the visible portion of the privacy-invading means entering your browser when you visit most sites. uBO's primary goal is to help users neutralize these privacy-invading methods in a way that welcomes those users who do not wish to use more technical means.

Installation
Firefox
uBO works best on Firefox and is available for desktop and Android versions.
Thunderbird
In Thunderbird, uBlock Origin does not affect emails, just feeds.
Chromium
Microsoft Edge Add-ons (Published by: Nicole Rolls)
uBO should be compatible with any Chromium-based browser.
All Programs
Do NOT use uBO with any other content blocker. uBO performs as well as or better than most popular blockers. Other blockers can prevent uBO's privacy or anti-blocker-defusing features from working correctly.
