$all (all network-based types + $popup + $document + $inline-font + $inline-script). Starting from 1.22.0, you can use the !#if false directive to disable a large block of your filters without having to remove them.īefore this version, you could use negated ext_ublock since this token always equals true in uBO. True on Firefox, Chromium 66+, supports style injection by tabs.insertCSS True when browser supports HTML filtering True on Safari (legacy, up to 12 / macOS Mojave) uBO supports only the following, and anything else gets ignored: Token įor the time being, only a single token is supported in a !#if directive (can negate using !). Support for preprocessor directives is the result of discussion with AG developers. For example, use this to create filters specific to a particular browser.įor example, to compile a block of filters only if uBO is running as a Firefox extension: The !#if directive allows filter list maintainers to create areas in a filter list that get parsed only if certain conditions get met (or not met). It is not allowed to load a sub-list located outside where the current one resides. The sub-list must be in the same directory as the main one. uBO will attempt to load the resource found at (the sub-list) and load its content into the current list. Other blockers will ignore the !#include directive because it will be seen as a comment and thus discarded. The purpose is to allow filter list maintainers to create filters specific to uBO while keeping their list compatible with other blockers. The !#include directive allows importing another filter list in place of where the directive appears. The pre-parsing directives execute before a list's content is parsed and influence the final content of a filter list. Pre-parsing directives prefixed with !# means older versions of uBO or other blockers will see the pre-parsing directives as a comment and discard them. UBO 1.16.0 and above supports pre-parsing directives. Keep in mind that generichide is a cosmetic filtering-related option, and using it has no negative consequence concerning privacy since cosmetic filtering has no privacy value. elemhide was only available as "No cosmetic filtering" switch. Supported starting with uBO 1.23.0, also aliased as ehide.īefore 1.23.0 it was translated internally to generichide. EasyPrivacy and other anti-tracking lists also contain countless so-called "generic" filters, and as a consequence, these would also end up being disabled. This option is not supported because using such a filter option would cause large numbers of filters to be silently disabled for a site where applied.įor instance, when used for a specific site, the genericblock option would cause all the filters in hosts files to be disabled, including those from the malware lists. Filters such as ||^ are still considered generic. Generic, in this case, means network filters without a domain= filter option. This option gets used with an exception filter to disable generic network filters on target pages. Note: it still works to negate strict blocking when explicitly enabled by blocking filter document option. The reason it is not supported is to be sure that users explicitly disable uBO themselves if they wish (through Trusted sites feature), not having some external filter list decide for them. The document option in static exception filters is for the sake of "acceptable ads" support, which uBO does not support. The document option used with an exception filter is to disable uBO. Not supported document for entire page exception Use sparingly, when no other solution is practical from a maintenance point of view - keeping in mind that uBO has to iterate through all the regex-based values, unlike plain hostname or entity-based values which are mere lookups. Example of usage: /img\.buzz/#+js(nowoif). Starting with 1.46.1b15, you can use regex-based values as target domain for static extended filters. 
Note that syntax higlighting is currently broken. Starting with 1.26.0 (commit one, two), very long filters can split into multiple lines: append space and backslash character to the first line and indent continuation line by four spaces. Here are the most surprising cases documented.
While uBO does not support some specific cases, it further extends the EasyList filter syntax, which also may share with AG's extended syntax.

You can refer to existing filter syntax documentation from Adblock Plus (ABP) and AdGuard (AG). UBlock Origin (uBO) supports most of the EasyList filter syntax.
