What to know before choosing

Install one blocker, not several. Stacking two content blockers breaks pages and slows browsing without blocking anything extra.

Most ad blockers are free because of an acceptable-ads programme or sponsored filter lists. uBlock Origin is the notable exception: it is funded entirely by community donations.
