This button exists to drive me insane. At least once a day, every single day, I accidentally click it when I am trying to click on my e-mail tab. I am the world's worst clicker. No, I'm not drunk. I just have bad aim, OK?!
Lolz. These are the woes of a 20nothing living in Manhattan. Goddamnit, right index finger! Why can't you be more agile? It is, like, sooooo annoying to have to reopen my Gmail tab and move it back to the left side of my Firefox window.
Yeah, you know what I'm talkin' about. Oh, you do.
