Ctrl-K seems to work for selecting the search bar in the v.4.0.

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.
