Adblock plus is on the way out, the new kid in town is µblock origin.<p>The difference ? 
Adblock plus can be extended to block trackers by adding block lists to the default, while ublock origin has those lists activated by default. 
Then adblock plus let through some ads they whitelist for money and supposedly good behavior, ublock origin has no such policy for the reason that ublock is the work of an individual who wants a better online experience while adblock plus is now the product of a commercial company.
