Just in case you don't know about it, and don't have something similar already - Read it Later is a gem of a program that makes it really easy to keep track of stuff you don't have time to read straight away. I use it to save and re-locate fic that I want to read, but don't want to add to my conventional bookmark folders. One click on a toolbar icon stores the link safely for me. Then, when I'm looking for something to read, I can browse the contents of the list.
Reviews are mostly positive but there are a few negatives, mainly dealing with other features of the add-on that I've yet to use (reading offline, for example). Still, it's been rated overall four stars.
It's quite possible that someone on my flist first alerted me to this add-on; if so, thank you! I use it a lot and find it really handy.
