adblock plus is commercial operated and is paid by advertisers to get whitelisted, akin to an extorsion mafia business. It's an ad blocker coming with tainted default settings. It used to significantly impact performances (not sure if this is still the case).
ublock origin is a one man personal project to improve his online browsing experience that he shared with the public and has become the goto reference. It has no whitelist or acceptable ads policy, is a general purpose blocker (blocks trackers, remote fonts, etc.) coming with sane default settings. It does not have the same performance issues adblock plus has.
In short: ditch adblock plus and switch to ublock origins.
