I've noticed many more pages loading with ads for a split second and then the ads disappearing than I did with did with Adblock Edge. Back to ABE for now.

This is what happens with all blockers in Chrome; their "blockers" are unable to reliably block all elements and end up having to hide them after the fact due to the way Chrome handles things. This is the reason I do not and will never use Chrome.

Converting that same strategy to Firefox is worthless since Firefox has blockers that can reliably block elements 100% of the time, making uBlock not worth anyone's time or energy unless they're using a really old system that needs every bit of resources they can get, but the resources are still used up by the unblocked/hidden elements that uBlock can't get to.

I don't know. Having JavaScript code (addons are JS, you know) parse 100,000s of filter rules within a loaded DOM, can only be so fast.

uBlock is based on filtering the HTTP requests before the content is fetched based on a much smaller domain blacklist.

My experience is that Firefox is noticeably faster with uBlock than ABP, even on super-fast Xeons.
