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

[n8chavez]

Or Brave. Built-in adblocker not dependent of MV2 or 3.

True, but the cosmetic filtering is not there yet. Brave and Vivaldi use rust independently of mv3, if I'm not mistaken. So, maybe this is addition to the built-in functions of either browser would pair well since there is an element picker with AdGuard mv3.

It might just come down to being the lesser of two evils for you then; a closed source MitM app versus obviously inferior (compared to MV2). That just might be the only two choices there are, if even Firefox chooses to adopt mv3 eventually.

They will move to MV3 but as per their words will retain current adblocking technique/provide alternate technology for the same adblocking capacity on top of mv3. If they won't do this, there is no point using firefox any further.

I'm using Edge with tracking on strict with the AdGuard Browser Extension v3 0.3.11.
The combination of a browser with an adblocker (Brave, Edge) and this extension is the best combination for a chromium-based browser for me.

If you have any issues with this extension, please report them to AdGuard.
(You can do that from the three dots in the extension)

Unfortunately new rules means a new (version) of the extension, that is one of the limitations of manifest V3.

Now that you mention it, how would that work with a custom imported filter?

I wouldn't be so sure of that.
Let's see what they will do after June 2023 when the MV2 enterprise support for chromium ends.
I do not know if the in-built adblock system of Brave is reliant on MV2 permissions and architecture.

Good question, I don't know...

Example of a bug report:

The bug reports are not optimized for the MV3 extension, so they couldn't reproduce the bug first
Now you have to wait for an update of the extension.
That's why reporting bugs at this stage is so important.

Brave adblock is built into the browser with Rust, i.e. it is not an extension, and therefore is completely independent of MV2 or MV3.

Technically, its adblocker is called 'adblock-rust'.

Native Rust module for Adblock Plus syntax (e.g. EasyList, EasyPrivacy) filter parsing and matching.

This is exactly what I needed to know. I switched to Brave last week because of all the MV3 stuff going on. I thought Brave had the best ideas as far as adblockers go. I did read here that Brave had the better built-in adblocker but was curious if it was still based on or dependent on Google. Brave is working great for me. Thanks for the info @oldschool.

C.H.

It still seems to be working fine here. But one thing I can see being a major problem is that, because there's no logger, you can't create an allow rule which bypasses a filtering rule. So, there's only two options: filtering enabled or filtering disabled. If there's any kind of problem with a site you'll not be able to see which rule is creating the issue and bypass it with a custom one. All you can do is disabled filtering altogether. Right? Or am I just retarded? (It's probably the latter)

Currently, disabling filtering is your only option, but if you choose to build the extension yourself and install via developer mode you can see which rules have been applied and manually add a custom rule.

Due to the fact that Chrome itself now blocks requests and shares statistics only with extensions unzipped and installed in Developer Mode, we can't implement the filtering log as we used to. But we can come up with a peculiar alternative, which we plan to do in the final version of the extension.

So, when you open the filtering log, an engine that works by the rules of Manifest V2 will be launched. It won't do anything with the requests, only show which rules may have been applied. By comparing the Chrome statistics with the results of the old engine, we will get a rough picture of how requests are processed.

The current version of the prototype does not implement a filtering log. Instead, filter developers will have to use the mechanism recommended by Chrome developers. The point is that you can still get information about which rule triggered. But there is a caveat: you need to install the extension in an "unpacked" form. That is, you will need to clone our repository, "build" the extension, switch the browser to Developer Mode, and only in this case you will be able to use the tools for debugging filters.

Also, we can't say what future developments will possibly introduce new (old) features.

Thank you @oldschool

I do not have the advanced technical knowledge so I wrongly assumed that since the brave adblocker is based on ublock origin code it might have some dependency on MV2.

I stand corrected

 

[oldschool]

I sent a bug report to Adguard re: MV3 version and have to say their support team is prompt and personal. Very smart to have this kind of support these days.

The bug I reported was re: Edge crashing when trying to close a single tab, which happens so frequently no matter what web page I'm on, I'm convinced it's a problem with Edge. Maybe sleeping tabs or some other feature is the cause.

Does anyone know how to write rules for Adguard MV3, e.g. block ping, etc.?

For what I understand, rules have to be coded into the extension. It dowsn't allow dynamic rules.

There are 'curstom filters' and custom 'user rules'. I'm not sure I know the difference.

I think you can write the same format as the manifest v2 extension.

 

[Mystic]

I will not use Adguard desktop for two reasons: firstly it is a paid and closed source software while the extension is free and open source. Secondly it works on the Man-in-the-Middle concept which I and many others on this forum don't like. I do the same with my Antivirus regarding MITM certificate hijacking.

Exactly my thoughts. I am using NextDNS now without any adblocking extensions. The only annoyance is some blank spaces on some websites, but other than that everything is great.

Then does it convert them to MV3 format? I see your image is of element-blocking rules.

 

[ForgottenSeer 77194]

I think yes

I believe other Chromium-based browsers should start to be less dependent on Google. It would be great if Brave or Vivaldi build their own extensions store, or better have a universal store that any Chromium-based browser can use. If things stay the way they are now, I believe every other browser, including Firefox, will follow Google on folded knees, unfortunately.
