uBlock-Mv3 – Port of Full Manifest V2 uBlock Origin to Manifest V3

Ported this in an evening because the policy finally kicked the bucket in my Chrome install. It works reasonably well and I haven't found any issues with stability or importing external rules yet.

uBlock-Mv3 – Port of Full Manifest V2 uBlock Origin to Manifest V3 launched on July 12, 2025 with 26 votes, #693 of 9,223 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.

In plain words

uBlock-Mv3 is a port of the full uBlock Origin ad blocker adapted to work with Chrome's Manifest V3 extension format. Created after Manifest V2 support ended in Chrome, it functions as a content blocker for web browsers. The extension maintains core filtering capabilities and supports importing custom filter rules. It is designed for Chrome users who want ad-blocking functionality following the platform's transition to Manifest V3 requirements. The maker reports stable performance with no known issues.

Full MV3 port of uBlock Origin - An efficient blocker for Chromium and Firefox. Fast and lean. - r58Playz/uBlock-mv3

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…from github.com

    uBlock Origin is more than an ad-blocker, it's a general purpose content filter that can be leveraged to hide low-quality content from pages you browse. While the main filter lists can remove mailing list popups and obvious nags, the definition of low-quality content is personal, so one size cannot fit all. I used to have an ad-hoc script to render and publish a personal uBlock Origin filter list, added to all my browsers. The goal of this project is to enable more people to build such a list custom list to filter out low-quality content and nags. Chose from a list of community-maintained…

    Firefox 149 ships adblock-rust (Brave's Rust engine, MPL-2.0) completely disabled with no UI. It's controlled by two about:config prefs with no WebExtension API, so you can't touch them programmatically from a standard extension. This extension gives it a UI: ETP toggle (via browser.privacy API, instant), filter list manager with clipboard helpers for the manual about:config steps, and 8 preset lists. You can also add your own if you so desire.

    Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better?

  • Ten years of running every day, visualized▲958

    Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  • Use Their ID – Use your local UK MP’s ID for the Online Safety Act▲862

    Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
