I just this minute tried it and NO, I don't like it, I might just be rolling back and then disabling the auto-update (again)
But, after saying that whilst typing this I have just noticed where a couple of my add-on icons are which I missed earlier, so there might be some light at the end of the tunnel after-all.
I see the 'Tabs on top' facility has now also been removed. (for moving the tabs so they are below the url/search bar and not on top of them)
Also quite quickly but where is the bottom information bar, I can 'quickly' see any where to display it. (even if it does give me a slightly larger screen)
