Time Blocked

This is a terrific concept, allowing you to voluntarily time-block websites that you have a tendency to stay glued to even when they're hurting your productivity. I used it to block FB, Twitter, and various news sites that can turn into timesinks during working hours, as I'm unfortunately low on discipline sometimes. There's one big bug, however. Let's say you block Facebook, but then you want to temporarily disable the blocking for a day, so you do. However there's no way to re-block the site - the icon completely goes away when you load that domain so you can't restore the setting. Or at least, I can't locate the means to do so. I would love to give a donation if this problem can be fixed. Basically the address bar icon should persist even if you have disabled the block for the domain.
