I'm hopeful for the speed improvements; I was having issues with 3.6.x in that and so far 4 seems good but I've not really stressed it.
Otherwise, confess first impressions are less happy. Moving the tab bar has left it stranded adjacent to neither the edge of the window nor the page which makes it less easy to quickly grab sight of for me, and I seem to have lost the shortcut for the search box which I actually _used_ - if this replicated the old suite's behaviour of location bar searching outside the history I'd mind less, but it doesn't. Having to grab the pointer every time I want to search instead of Ctrl-E doesn't seem a win to me :-(
Thanks; I wonder why they changed it but didn't put a tooltip on the component advertising the new shortcut? I'm sure that used to be there on at least some older versions of Firefox.
Ctrl+k has always worked, it is not new. (And as long as I can remember has been the "primary" short-cut.) They wanted Ctrl+e to be available for tab group functionality: https://bugzilla.mozilla.org/show_bug.cgi?id=592183
We can kill old keyboard shortcuts. There are two for focusing the search box (ctrl/cmd + e, ctrl/cmd + k) and technically only one is needed. Many of these things are here for legacy reasons supporting users of IE5 and Netscape 3. That can, thankfully, go away.
