Ditch it! Use a better alternative.
I switched to uBlock Origin because ABP was getting too big and too shady (block ads then turn around and demand money from sites to show the ads anyhow). As a bonus, it's also much less of a pig.
There's also uBlock (no Origin) and there's some fork drama there, but I don't really care, either is better than ABP now. I think uBO gets more and better updates though.
