This is SO handy. I use it all the time. Great for web research when you want to keep track of (or send to others) the list of URLs you've perused. Good for tech support, too.

This tiny add-on does all that it says, seems (from what I can tell) bug-free, and has a low overhead. And it's free! This is one of my staples for browsing.
