Content filtering can be added to Firefox, Chromium-based browsers, Opera, Safari, and other browsers with extensions such as AdBlock, Adblock Plus, and uBlock Origin, and a number of sources provide regularly updated filter lists. Even an inexperienced user can get rid of the ads, since AdBlock Master starts working right after the installation and doesn't need any additional settings. These extensions allow users to block some or all banner ads and other advertisements that appear on Web pages. To close Safari: Click Safari in the top-right.
