The project I'm currently working on has lots a stuff done via cookies. And it's been a pain to go each time through the settings, show only the localhost cookies, and delete them.
I finally had a good idea this morning : why not make a browser extension? So during my lunch break, I made this chrome extension. It's quite simple, not a lot of code, and it does one thing only : remove all your localhost cookies.
Since I'm mostly using chrome, I don't have the need to add other browsers support, or other features, but maybe I'll do it anyway, for the sake of learning (and the small hope of maybe being useful to somebody, somewhere).
