IDK. BluHell was always pretty light, which was one of the reasons I chose it over ABP. But we will see what happens.Absolutely nothing. If uMatrix is the end-all blocker (which it has been, from what I've used of it), then by default, BluHell should be cornered.
It should speed TFF up, because that's one less add-on to initialize.
Was that your experience when you removed it?
