If you're still using Chrome now is the time to switch to Firefox. This is an interesting experiment but the only solution is to stop using Chrome.

You can also use Brave, which implements its own native adblocker and isn't impacted by Manifest v3.

Do you mean that particular adblocker is not impacted or is Brave going to maintain support for the APIs dropped by Manifest v3?

Brave's adblocker is internal and written in Rust.

I'm pretty sure it's also faster than any adblock extension like uBlock.
