Ublock Origin also already has an “AI widget” blocklist you can enable. Literally the only extension that keeps me on Firefox because of how useless it is on Chromium.
Assuming you're talking about Manifest V2 deprecation: you can disable it in Chromium-based browsers by launching with `--disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled`, and enjoy uBlock once again.
