Firefox is now the last major browser that still supports uBlock Origin

Anyone can build a custom extension to do anything an extension is allowed to do. I had ~7 standard extensions that I pretty much always install into chrome browser. Over the past month or so I've been using Claude code to build a single custom extension that handles all of the things I used 7 extensions for previously. One extension does everything. You can even use the existing extensions you already use as guides for Claude to make sure all of the features you want are included. One extension to rule them all!

Thank God for the Brave browser. For those disliking their built-in adblocker, there is a Manifest v2 opt-out specifically for uBlock if you need it.

Firefox, after 20 years, once again has an advantage over the other browsers. Let's hope for new generations to get tired of so many ads to finally ditch chrome.

Ads are so invasive and prevalent now that you need an ad blocker just to use the internet.

Firefox is also the only browser that vets uBlock's code on every update to make sure the developer hasn't inserted spyware or malware into the extension. They don't do it for every extension, but they do so for a wide selection of popular options. > Recommended extensions differ from other extensions that are regularly reviewed by Firefox staff in that they are curated extensions that meet the highest standards of security, functionality and user experience. After receiving Recommended status, safety standards are maintained through automated checks, monitoring, and periodic technical reviews https://support.mozilla.org/en-US/kb/recommended-extensions-...

You can also run Ad Nauseum if you want to

Vivaldi 8.1 still supports it (Chromium 150) as loaded unpacked extension. Edit: and latest August 14, 2026 Chromium 152.0.7977.38 based Snapshot https://vivaldi.com/blog/desktop/address-field-calculator-an... has this in patch notes: "[Extensions] Re-enable and extend Manifest V2 extension support for the time being (VB-130324)"

What's funny is that extensions were supposed to be a way to let you do the things the browser didn't want you to do. Guess that was a bit too much freedom for Google to accept, so they had to make a store with a gate, and destroy the APIs so that they're useless. Then they had to make up some reasons to justify that and ram it through the pipeline despite everyone's objections, and the frog got boiled. Now we're back to needing an actual extension system that does what extensions were supposed to do in the first place.

Manifest 3 is why I finally shut down Sitetruth and Ad Limiter. Removing ads from Google Search is now possible only in Firefox.

Does it really make a huge difference to keep supporting Manifest Version 2? I've installed uBlock Origin Lite in my Edge browser and I don't see any ads there either.

I just use Brave. I haven't seen a YouTube ad in years.

Support Firefox. F** Chrome.

It is possible to write your own extension and still use it in Chrome as long as it's not bundled. It would be a huge pain to get the source for uBlock origin and implement it locally yourself, but it might be worth the pain to block ads.

For those who use uBlock Origin Lite, have you noticed any issues/deficiencies in what ads are blocked? I haven't.

I've been using Firefox for over 6 years now and I've never regretted it.

Wtf, simply not true: Brave: chrome://flags/#brave-extensions-manifest-v2 > brave://settings/extensions/v2 > Enable uBlock Origin (Brave-hosted, even better). Helium comes with uBlock Origin pre-installed. Edge even still has it https://microsoftedge.microsoft.com/addons/detail/ublock-ori... And I'm sure others ...I personally only use/test Brave, Brave Origin, Helium and Firefox.

Do people not remember Firefox changing their terms of service last year and allowing them to sell your data to third parties? I don't get it did people forget? I switched over to LibreWolf and other browsers like that then and never looked back.

uBO + Steven Black hosts list + firefox. Peace, for now at least.

Are there any Chromium-based mod/plugin loaders out there? I mean something that uses the same DLL/SO hijacking or injection tricks game hackers use to build mod loaders, to expose a hooking layer for plugins.
