Hello, I have a lot of stuff to do, and I'm easily distracted. Like many people here, I spend too much time websurfing (or reading MacRumours!) when I should be working. I'm looking for a simple app that with a single click will cut off outside access for firefox (and maybe certain other apps) for maybe an hour (user definable) I'd rather not disable firefox itself (I use it for testing web-building, and also for the Remember The Milk todo app) and I don't want to just unplug the internet (I need emails, ftp, etc to still get through. I know there's this strange thing called willpower (!) but mine needs all the help it can get to stay focussed on the job in hand, not wander off websurfing. I've fiddled with OSX parental controls, but they're not up to it, and tried out Little Snitch, but it can't impose a time-limited block. Advice?
