If you're tired of hearing the word "millennial," this extension is for you. It changes the word "millennial" on every webpage to "pesky whipper-snapper" instead.

A mustache enthusiast will appreciate Mustachio. The feature adds a thick black mustache to every photo on a website.

If you go on the Internet and think, "Hm, I'm not seeing enough Nicolas Cage," this extension is here for you. The nCage will exchange every photo you see with an image of the actor.

(If Nic Cage isn't your type, there's always the Hey Girl extension, which replaces every photo with a shot of Ryan Gosling.)

For the Facebook-obsessed, this extension updates users every single time someone unfriends them on the social network. That's right, you'll get notified every time someone decides they could do without your status updates.

The Nothing extension literally does nothing. However, it's received 6454 reviews and currently has a five-star rating. Oh, Internet trolls like to have fun.

Maybe you can deal with millennials, but if you just can't stand Miley Cyrus, the Chrome gods heard your prayers. No Cyrus hides all mention and photos of the singer from your web pages, so you can comfortably surf a Hannah Montana-free zone.

Jailbreak the Patriarchy is a gender-bending feature that swaps every male or female phrase. "He" gets replaced by "she," "mother" gets replaced by "father," and so on. The extension's site lists this example: If you see the sentence "He loved his mother very much," it would instead read as "She loved her father very much."

Nope, not confusing at all.

Fans of the Internet meme can Doge-ify their websites. The addition will plop Doge photos and sayings such as "so wow" everywhere.

This extension is intended more for you to prank others than to use yourself (because...why would you want this?). Upside Down does just what it says, flipping over every website you open.
