better than adblockers for blocking domains, files by extension or type, and better than having hosts files in system, the only inability which can be compensated with ublock is blocking specific elements and hiding them without blocking whole website or all files, has so much abilities and easy to backup lists, one of my best extensions!!! also gives perfect picture of websites and elements on it, useful for winhttrack, also useful because can make files and localhost work offline by blocking 3rd party for file and localhost
