it supports it and the dev for ubo has outright had benchmarks that ubo blocks more stuff on gecko engine based browsers vs chromium based browsers even during manifest v2 era.

Apparently Firefox still supports MV2.

They do, but it should also be noted that Google’s implementation of MV3 was specifically designed to target adblocking and we know this because Firefox’s implementation of MV3 still enables full adblocking capabilities. So even if Firefox does away with MV2 entirely, uBlockOrigin can work with their MV3.
