Do this only when you’re really, really bored with life. ZDNet:
Firefox maker Mozilla has a website that allows you to spawn 100 tabs designed to confuse ad trackers
First, you visit the site and you choose a category from four available — Hyperbeast, Filthy Rich, Doomsday, or Influencer. Then you click a button saying that you agree to have “100 tabs of pure madness” spawned, and after being given one final chance to back out, it does what it says on the tin and opens 100 new tabs, each containing websites related to the specific category.
It takes awhile.
