Ever come across something funky in production and want to see it in your development environment? Use Pow? This is for you. Make a new bookmark for this location:
javascript:(function()%7Bif%20(%2Fhttp%3A.*%5C.dev%2F.test(window.location.origin))%20%7Burl%20%3D%20window.location.href.replace(%2F%5Ehttp%3A%2F%2C%20'https%3A').replace(%2F.dev%2F%2C'.com')%3Bwindow.open(url)%3B%7D%20else%20%7Burl%20%3D%20window.location.href.replace(%2F%5Ehttps%3A%2F%2C%20'http%3A').replace(%2F.com%2F%2C'.dev')%3B%3Bwindow.open(url)%3B%7D%7D)()
If you want to edit this, first copy and paste the JavaScript below into a bookmarklet creator. I used http://mrcoles.com/bookmarklet/ but others might be nice, too.
