I've been using a plugin for firefox (on my PC) called screengrab, but the plugin isn't available on FireFox for mac. It's an awesome plugin - basically it allows you to take a screenshot of an entire window in firefox, no matter how long it is. So far it's the only plugin I've found that let's you do it within firefox. I know there's a utility for OSX that lets you input a URL and it gives you a full page screenshot, but the problem is a lot of the time I need a screenshot from a website I'm logged into (email, college transcript, forums, etc.) so the app is somewhat useless in that regard since it doesn't work if you need to login. Are there any other solutions for the mac? Please help me out!
