The other extension is Pokémon No by developer Conor Browne. This one is similar, but claims to eliminate Pokémon mentions from any page online. In the above video it tries its magic on Google. The difference here appears to be that the extension removes the actual text about the game and not the entire post, while Pokémon Go Away removes full posts out of your Facebook or Twitter feeds.
Pokémon No also has to be activated on each individual page, which may actually make it a little more useful for users who play Pokémon Go, but need a few Pokémon-free sites as a safe space.
So there, now there is brief refuge from Pokémania 2016. But if you really want to get away from it, you'll probably have to throw your computer out the window and buy an abacus.
