After updating to F11, my firefox window no longer had the "activity indicator" / spinner / throbber / progress thingy icon that shows when network activity is happening, which makes it difficult to tell what Firefox is doing. I created a clean profile to make sure that this wasn't just a problem with upgrading existing ff3 profiles, and the new profile had the problem too. You can fix this by hand with View->Toolbars->Customize, so the code is all still there and working, it's just that the default layout is broken or something.

I have two ... small thermometer in the status bar on the bottom of the window and changed label of the current tab. Which one you mean? (both of them work for me, but anyway)
I meant the firefox 3.0-style spinner at the right end of the menubar. Ah, I see what's happened. 3.5 defaults to "Always show the tab bar", and so you always get a spinner per-tab in the tab bar and so you don't need a global spinner in the menu bar, and so presumably the Powers That Be removed it because it was redundant. But now if you turn off "Always show the tab bar" (which I did, because I was used to the old way), you don't get any spinner at all... Maybe the menubar spinner should appear if you turn off "Always show the tab bar"? Or else "Always show the tab bar" should be removed from the prefs dialog.

You have certainly a point, and it is quite interesting, but quite certainly this something which needs to be resolved UPSTREAM.
