Ad-blocking filters limited to 1

[Ucinus]

Description of the issue:
Starting today, I began receiving a popup informing me this: “Your browser has modified the list of active built-in filters” and apparently now only 1 filter can be active at any time.
I am also using AdGuard and Malwarebytes browser extensions.
From what I understand, all my security filters I had in place for my browser are now inactive and this is a big issue.
I understand that Chromium is the reason, but they reduced the list back in 2024, why wasn’t I affected until now? Did Brave have a workaround for that limit, and it worked until now?
If there will be no updates with a fix for this shitty situation I will switch to other browsers → maybe firefox.

Exact URL of the website in question:

@fanboynz is the Brave team member who will know how to help you.

Phone freezes every time with custom content filters on Android

Many of these are already included, so you’re doubling up. Also we don’t support many of the Adguard rules so that may also cause issues

Brave does not apply enabled built-in rules

Erm, we use uBO lists as part of Shields. Adguard isn’t needed for us. Not sure how this makes “zero sense”.

Hey, just out of curiosity, which one are you referencing? Are you speaking about the content filters listed under Content Filtering, such as below: [image] Otherwise, AdGuard isn’t part of what Brave does. The native filters used by Brave are essentially what you see below: [image] If you enable Fanboy's Annoyances and uBlock Annoyances then it becomes: [image]

Ok, I will wait for a reply from @fanboynz then.

No limits in Brave, probably related to Malwarebytes extension? Would recommend not using (the extension) with Brave since we have shields

[Ucinus]

even after deactivating the malwarebytes extension, I have the same message.

@Ucinus can you try creating a new browser profile (Menu --> more tools --> Add profile) without the extensions, close your original profile window and test to see if you can enable multiple filters in the new profile? Where exactly does this message display?

On my end I don’t have any issue enabling multiple filters in the browser on Windows or macOS.

im also using malwarebytes extension as it blocks things that brave sheild just dosent but no problem on my end i am on linux tho

It seems that making a new profile resolved the issue for Malwarebytes but the issue is still there for AdGuard - but in the end I can live with it. The message appears when I open Brave (in the lower right corner) and every time I go to AdGuard extension.
