AdGuard publishes the world's first ad blocker built on Manifest V3

https://adguard.com/en/blog/adguard-mv3.html

tldr: As expected V3 ad blocking will be worse than V2 (e.g. uBlock Origin) with devs having to deal with work arounds and deal with a limited number of rules.

The last phase of the launch will come very soon: starting in January 2023, all extensions on Manifest V2 will stop working, even those that were added to Chrome Web Store earlier.


For static rules, Chrome set a minimum guaranteed limit of 30,000 rules per extension and a total limit of 330,000 rules for all extensions installed by a single user (this also takes into account the limit of 1,000 regexp rules per extension). The trick is that one extension may get all of the allowed amount of rules, or there may be more than one, and then perhaps some of the extensions will fall short of the limit.


Conclusion

Despite the limitations of Manifest V3, AdGuard MV3 still protects against ads and tracking quite well:

  • Blocks requests to trackers proactively
  • Hides banners, social widgets and other annoying elements
  • Blocks adverts on video sharing platforms, including YouTube

Although the experimental extension is not as effective as its predecessor, most users won't feel the difference. The only thing you might notice is ad flickering due to the lag in the application of cosmetic rules.

Our goal with this prototype is to test the new approach and get your feedback. So please, try it out and let us know what can be improved. As usual, this prototype is open source and published on Github. If you have any issue with it or have any suggestion, please post it to Github and we will listen.

By releasing an extension built with Manifest V3 today — first among developers of ad blockers – we can say that we've met the challenge that Google posed to us. There is still a lot of work to be done, but we can already claim that even after the discontinuation of Manifest V2, Google Chrome users will be able to protect themselves from ads and trackers with the AdGuard Browser Extension.

Hopefully the millions upon millions of fricking r-slurs that use Chrome will start moving away from it because of this shit :marseyclueless:

Surprisingly a bunch of people I know don't use chrome anymore, they have moved to one of the chromium forks like Vivaldi, Edge, or Brave. It happened before when everyone moved from Firefox to Chrome, and it looks like it could happen again.

Firefox and Opera are the only "major" non-chromium ones left

Opera is chromium as well. The only mainstream non chromium browser is Firefox and it's forks. I think chromium is here to stay, Firefox fans don't want to admit that chromium is a better engine than what Firefox currently uses (Gecko). I don't think people will leave chromium, just Chrome itself.

Just because it's true doesn't mean u need to say it.

That being said firefox is better is every other way

It's a mixed bag. While Firefox is better than Chrome, both are inferior compared to the forks that exist. Chrome is trash because features randomly appear and disappear with no warning and it's frustratingly inconsistent. Firefox has a bunch of bloat and has made some very stupid decisions, such as adding ads to the browser once or twice.

Tbh I only recommend Brave, Bromite, and Librewolf to people. Even then none of them are perfect, every browser has at least one big issue with it.

Will Firefox ever switch to a new engine based on Rust? Wasn't that kinda the whole reason Mozilla sponsored Rust development?

You are correct. They actually had a Rust engine (Servo) in the works, but they cancelled it and fired the whole team. Mainly cause the CEO is too busy raising her salary and trying to censor the internet. Mozilla is a corpse still walking at this point. Glad Rust is mainly community developed, as it's actually pretty good.

Oh shit they cancelled it? That sucks, I thought it was just taking longer than expected.

Nope, project is dead. They started adding some of the servo parts to gecko, but none of the really important stuff imo.

Opera too? Well dang

Yep, Firefox and it's forks are the only real options for everyday use that aren't Chromium. Pale Moon, Lynx, GNOME Web, Konqueror, Basilisk, and Otter Browser are all also not Firefox or Chromium based, but none of them are really usable for everyday use atm.
