"Suggest to search for the input"

[c02y]

If you check/enable the "suggest to search for the input", the Enter key(after paste or type the website url in the address bar) will do nothing for a website you never visited, the web site won't be loaded in Firefox anyhow.

But if you unchecked it, it won't auto complete the address bar(such asyou type github, it won't complete it into github.com in the address bar, you have to type all github.com or choose from the drop list manually).

I don't know it is a bug or not.

Since Firefox 33 for me, ENTER key won't work when "Suggest to search for the input" is selected.
For me, it won't work at all, no matter what you type (visited site or not)
If unselected, ENTER key comes back :) I couldn't reproduce the issue met by CodyChan though, maybe because I have "Automatically select the first result" checked. Or maybe because I don't fully understand the issue ;)
