Comment 1 for bug 681869

I would say that updating the tooltip would be a good way to indicate what is happening. So you can mouse over the icon if you want to know what the immediate action is, but it shouldn't pop up an bubble on each action.

I haven't used Dropbox to compare. However, I expect bubbles to only occur when I actually need to do something. They are a way of getting *my* attention that there is an action I need to perform. Something like "conflict occurred" would be a reasonable popup. Having it tell me it is doing what I asked it to do is a bit odd.
