The title says it all; I've seen a few people discussing this about the Chrome addon as the description says it blocks but doesn't actually remove the code for ads in the browser. How does Adguard do this for Firefox? Does it remove the code or simply blocks the visible ad, and how does Adguard compared to Adblock in this regard? If it only blocks the ad, can malacious code from malacious ads still get through the browser? Thanks for any information!
