The main reason uBlock on Firefox works better is because of CNAME de-cloaking. All the tracking shit that appears to load as first-party, but isn't, can be correctly detected and blocked on Firefox. On Chrome it cannot, and with Google, Facebook, et al. encouraging site owners to move to these fake first-party conversion tracking solutions, your exposure to profiling has increased dramatically. You may see fewer ads but it does not do the same job.
