After a little homework, I found that not only can it be done - but it's very easy. Follow this link: http://www.furl.net/tools/install
The instructions are there, but FYI all you need do is click on the link (I clicked on the "Basic" button at the bottom for my Chrome browser) and without letting go, drag it to Chrome's shortcut bar. That's it!
I'd also signed into my account when I put up the button. I don't know if that needs to be done or not - all my stuff was there and ready to roll.
Chrome rocks, doesn't it?!!
