Blocks specific sites from appearing in Google search results

Description

This extension prevents the sites you specify from appearing in Google search results.

You can add rules on search result pages, or on sites to be blocked by clicking the toolbar icon. Rules can be specified either by match patterns (e.g. *://*.example.com/*) or by expressions including regular expressions, variables and string matchers (e.g. /example\.(net|org)/, path*="example"i, $category = "images" & title ^= "Example"…).

You can synchronize rulesets across devices via cloud storage (Google Drive, Dropbox, OneDrive, WebDAV) or browser sync.

You can also subscribe to public rulesets. Some public rulesets are listed on the website: https://ublacklist.github.io/rulesets

Browser support policy

uBlacklist supports the following browser versions:

• Chrome: Latest stable version only
• Firefox: Latest stable version and latest ESR only
• Edge: Latest stable version only
• Safari: Latest stable version only (macOS and iOS)

Support for browsers outside the list above depends on community contributions. Please open a Discussion with a concrete implementation proposal — reports without one are unlikely to be addressed.

For subscription providers

To publish a ruleset as a subscription, place a ruleset file encoded in UTF-8 on a suitable HTTP(S) server, and publish the URL. Here is an example hosted on GitHub:

https://raw.githubusercontent.com/iorate/ublacklist-example-subscription/master/uBlacklist.txt

You can prepend YAML frontmatter to your ruleset. It is recommended that you set the name variable.

name: Your ruleset name

*://*.example.com/*
