For people that have somehow missed the story, manifest v3 removed support for certain powerful network apis, severly limiting ad-blockers capabilities. uBlock Origin will not work anymore without manifest v2 (there's a v3 compatible lite version of uBlock Origin).

I saw there is a manifest v3 ublock lite.

I don't understand why and how it would be less capable, and so far I have not read the details of how/why.

So far, it's just rumors to me.

I will keep using firefox anyway, but honestly I am still waiting for a clearer explanation.

You can't just call stuff you simply don't bother to look up "rumors".

Read up here:

With manifest v2, the extension could dynamically intercept requests and block them based on a custom rule.

With v3, extensions have to predefine the rules for blocking. Which is the limiting factor

So because you don't understand it, its rumors? A Simple google search would answer all of your questions in a literal sentence. It removes APIs used by ad blockers.

That and certain features like the element zapper in uBO aren't available in Lite.

And there's a limit of 5000 such rules.

The limit is 330000 rules:

"Based on input from the extension community, we also increased the number of rulesets for declarativeNetRequest, allowing extensions to bundle up to 330,000 static rules and dynamically add a further 30,000." https://blog.chromium.org/2024/05/manifest-v2-phase-out-begi....

even if it was infinite that wasn't really the issue, you can't express the algorithms uBlock Origin is using as a static list

Given the size and complexity of modern ad malware I doubt if 330,000 rules is enough, so why limit it?
