I think the best compliment I can pay Aza Raskin is that whenever I look at one of his designs, I know immediately that it's his. He's got a focus for circular designs combined with an emphasis on minimal displays that convey a lot that's a signature look in my mind.

This stuff he's doing for Mozilla thrills me. It's great to see him working with a huge company.

I'm a bit skeptical. The circle is loved by designers, but it does not seem to survive in software that is actually being used by people. There are few pieces of software that uses circular control elements - the few that I can think of (the logitech mouse, LabView) don't handle well.

In this case, the design doesn't function as a circle. It changes to a linear list once you move your mouse. The circle is just there as a placeholder.

Have you used Raskin's music site Songza? It's a great example of circular navigation that works really well.

To support markessien's point:

I used to love this extension, until it became incompatible with a new FF, whereupon I promptly ditched the mouse.

A point in support of neither: the circle is an excellent design element in gesture-related selections because all edges are equidistant from the center. Duh. The not-duh part is this: usually 8 arcs is the best division of space, but 8 is a bad number. It's not too big nor too small, and using the circle leaves you little wiggle room, such that you start constraining your design decisions to it.

When it works, it works great. When it is slightly off, it is quirky, because it is tempting to just throw in some extra options to fill up the 8 parts of the circle.

It does not work for me personally. I don't like the way that the options appear in places that I did not predict they would appear in. When I interact with anything, I want it to behave exactly the way I expect it to behave, and to do so consistently.

The songza site does not behave as I expect it to, and even after I learn how it works, it does not behave consistently in its own mould. I click an item and up pops some 4 arrow thing. When I move over some arrows, yet more things pop up and on some other arrows, more things don't pop up, and there is no hint as to which will cause things to pop up or not. So even though one might learn how such a navigation works on that particular site, as soon as you go to another site, you will have to relearn again which of those arrows will cause popups and which will not. Contrast that to a right click menu which always indicates which options will pop out.

I don't think circles are good navigation tools, for the reason that there are very few popular tools which use circles as their main navigation mode.

It seems like you are not arguing against circular navigation in general, but specifically the navigation on songza.

Your problem with the unpredictability of the menus in the songza-style navigation could very easily be fixed by simply adding an arrow to each item that contains a submenu, just like the typical context menu.

An arrow could be added on the tip of each leaf of the songza navigation circle that uses has a submenu. The arrow would visually indicate that a menu will pop out if the mouse hovers over leaves with these arrows. This would function exactly as the arrows on the typical context menu.

I don't get the point. The only time a blank tab opens is when you're typing in a URL or search phrase, at which point your eyes are on the chrome anyway. If the Cognitive Shield has any perceptible load time, it's not worth it. Granted, at least it doesn't look like an error message like IE7's default blank tab.

The mission is to make it possible to click some easy links without the visual clutter that other browsers' start pages give.

Have you not seen Speed Dial/Chrome/Top Sites? Because this is the exact same functionality as those other ones, and none of them have perceptive load times. Firefox is playing catch-up here: it's not giving anything particularly new.

Chrome's tab-selection of top pages is a lot more useful to keyboard-centric users... anytime I have to move my hand to the mouse is time from my life I'll never get back!

A certain improvement would be to, instead of hitting tab-tab-tab-tab-tab-return, I could just hit alt-5...

Knowing Aza this will very likely support keyboard navigation. Aza's a stickler about having things ultra-accessible.

The big flaw with this design (the initial circle), of course, is what if a site doesn't have a favicon?

Odds are it's not one of your favorite sites if the site owner isn't even committed enough to have made a favicon.

Before you smack the reply button to pop up with "But here's an example of my favorite site without a favicon!": I said odds are.

I doubt the number of favorite sites without a favicon is low enough at this point that Mozilla shouldn't spend a lot of time worrying about it.

The example picture has two sites with the same favicon, so the general-case problem probably isn't all that uncommon. Especially if you're the sort of user who does things like checking multiple twitter pages without an RSS feed.

This looks like an awesome idea. I haven't been able to try it out yet because I'm running FF 3.07 (simply because Ubuntu repos haven't brought it up to 3.1 yet, and I don't really want to bother that much atm), but it reminds me of the controls built into some FPS's and even old Lucasarts Adventure games like Full Throttle or Grim Fandango. Except the default actions in this case are all favorite websites. Nice to see Mozilla labs pushing the envelope yet again.

Something else I'll promptly be turning off/removing ASAP when I am forced to upgrade to a newer version of Firefox. Firefox was at its best in 1.5 -- hardly anything after that has been anything but developer flights of fancy.
