I'm really enjoying all of Google's FireFox extentions. They really make my web browser much more pleasurable. I think the best one of them is the Google Browser Sync. The last several years have been spent always trying to save my favorites and get things the same on my work and home computers. That is a challange no more. I think I'm going to buy some books so I can learn to create an extension or two myself.
I made a post on my Amazon Web Services blog earlier today. It had nothing to do the Google FireFox Extensions, but definately worth a look as always.
