I'll preface this with, I don't have a better solution, so kudos to the FF crew for trying something new. That being said:

I don't find this compelling at all. Do I really want to spend part of my time browsing, by sorting and organizing my tabs into folders?

Did this ever work for email? I'm pretty happy with the Gmail model of searching instead of organizing, although that probably wouldn't work for tabs.

The idea is that you organize it as you go, rather than repeatedly wasting time every time you have to figure out which tab a page is on by scanning the tab bar.

As other people have stated in past threads, there's plenty of room in the idea for automated organizing to be implemented later.

I tried the addon (FF4 only), you don't really have to organize them all the time (at least from my experience).

If you have 1 tab open, and then click on a link, and open it in a new tab, it will automatically be grouped together with the "parent" tab.

One personal problem I found, it's just that I need to see the tabs all the time, while in this way the other groups are hidden: to see them with this addon you have to click the addon icon (navigation toolbar) or access it by shortcut.
