I'm trying to migrate from Chrome to Firefox under OS X and this issue is extremely annoying. In Chrome pressing the Cmd key is a universal for "do this in a new tab" command. It works for addresses, search and clicking on links.
In Firefox for some reason they decided to use Cmd for new tab when clicking but Alt/Option for new tab when entering something in the address bar.
How can I remap the address bar and search from Alt + Click to Cmd + Click?
