Download: uBlock Origin
uBlock Origin is, at first glance, an adblock tool. It’s also a great security tool. With an easy-to-use dashboard, toggling security and adblocking is a snap.
After installing uBlock Origin, make sure to set up the adblock lists. By default, only the adblock script EasyList is enabled, but there are a number of extra available right from the dashboard. Of course, if you’ll be using Anti-Adblock Killer Continued, click this to enable AAK-Cont rules for uBlock Origin.
