New Product Idea of the Day

I look forward to anyone who might know of something that can do this:

1. A bookmark saver tool that on one click will let me save all my open tab windows in firefox but only for a specified period of time - say 2 days. I always end up with all these windows open with these great articles i want to read, but then something comes up and I have to go. Leaving them all opened is annoying - bookmarking them when i only want to read rather than save is annoying....I need more an in the moment and then self-destruct kind of bookmarking tool.
