All of them. UBlock Origin does not work on V3. There was a Lite version that used V3 but they stopped work on it because it was so limited. It looks like there's been some updates to it recently now.
The size of blacklists has gone from unlimited to a limited size. The blocking ability has been limited. And the worst of all, blocklists have to be bundled in extension updates and not downloaded. While they have increased the limited blocklist size for V3 overtime, I don't know if they ever changed the other limits.
