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.

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

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?
