uBlock Origin – filter lists and advanced features

uBlock Origin depends on lists that are edited manually every day. The default lists are enough to replace extensions like Ghostery, Privacy Badger, DuckDuckGo, and MalwareBytes.

Some things, like cookie banners, aren't blocked by default. To block them, you have to select additional lists in the Filter lists pane.

The lists mentioned below are crafted carefully and seldom cause problems. If you suspect uBlock Origin is hiding something important, use the "No cosmetic filtering" toggle. The ⏻ Power button disables uBlock Origin altogether for the current website.

The extension also offers a logger that tells you what filters are being applied to each website. To report broken websites or ads directly to the uBlock Origin project, use the 💬 Report an issue button.

Recommend filter lists

Keep all default lists selected. If necessary, go to the Settings pane and scroll down to find the Reset to default settings... button.

AdGuard – Annoyances²	Hides "Disable your adblocker" banners, blocks self-promotional ads ("Use our app", "Subscribe to our newsletter"), skips link shorteners and timers, pauses auto-playing videos on news sites, and allows copying text from websites that prevent it.

Google sign in prompts

Some people find the Google sign in prompts that appear on third-party websites useful, so they aren't going to be hidden by these lists. You can add a custom filter manually to block them:

• Open your uBlock Origin settings
• Click on the My filters pane
• Paste this filter: $3p,script,xhr,to=accounts.google.com,from=~google.*|~youtube.com
• Click on Apply changes: example screenshot

Connections to Facebook

Instead of installing a separate list or extension to prevent Facebook from tracking you, simply block all third-party websites from connecting to it:

$3p,to=facebook.*,from=~facebook.*|~instagram.com|~messenger.com|~meta.*|~threads.net

Youtube Shorts

Use these filters from /r/uBlockOrigin.

Create your own filters

• Element zapper - hide things temporarily
• Element picker - hide things permanently
• Static filter syntax
• Resources Library
• Start a thread on /r/uBlockOrigin if you need help writing your own filters

Advanced features

Overwrite CSS styles

If you know CSS and use it to customize websites, you can replace Stylus with filters such as:

! change the text highlight color on all sites *#$# *::selection { color: #000; background-color: #fc0 } ! number of thumbnails per row on frontpage and channel pages www.youtube.com#$# #contents.ytd-rich-grid-renderer{ --ytd-rich-grid-items-per-row: 5 !important; } ! hide websites from search results duckduckgo.com,www.google.*## :is( body.body--serp article, body[data-activetabid="images"] li, body#gsr #search .MjjYud:not(:only-child), body#gsr #search div[data-attrid^="images"] ):has( a[href*=".bab.la"], a[href*="quora.com"], a[href*="example.com"] )

Redirect internal URLs

To rewrite paths within the same hostname:

! redirect /en-US/ to /ja/ at addons.mozilla.org $doc,uritransform=/^\/en-US\//\/ja\//,to=addons.mozilla.org

This filter will only work if you check Allow custom filters requiring trust at the top of the My filters pane.

Note that special characters need to be escaped in replacement strings too, so use \$1 instead of $1.

Set cookies and localStorage items automatically

If you've configured Firefox to clear all cookies on exit, you may want to make uBlock Origin restore some data automatically with set-cookie and similar scriptlets:

! skip duck.ai onboarding duckduckgo.com##+js(set-cookie, dcm, 3) duckduckgo.com##+js(trusted-set-local-storage-item, aichatWelcomeCardsDimissed, 1year ) ! skip age verification on Steam store.steampowered.com##+js(trusted-set-cookie-reload, birthtime, -1072987199, 1year)

Replace NoScript with uBlock Origin

uBlock Origin can also fully replace NoScript:

• No scripting - disable JavaScript by default and/or toggle it on a per-site basis
• Medium mode - filter scripts and frames based on their source and target domains

Dynamic filtering rules created from the GUI may sometimes be too specific, for example: * some.website.cdn.example.net * noop. To avoid having to add exceptions for different subdomains manually, open the My rules pane and edit it to * example.net * noop.

It also supports generic TLD rules: uk uk * noop disables dynamic filtering for all connections between different .uk domains.

Make frames "click to play"

! block frames from these domains (not necessary if you use medium mode) $3p,frame,to=example.com|spotify.com|example.org ! show "click to play" placeholders for blocked frames $3p,frame,redirect-rule=click2load.html,to=example.com|spotify.com|example.org

Userscripts

Run custom scripts with uBlock Origin: userResourcesLocation (read the information at the top of the page).
