Just as a warning, Firefox 43 has fucked with the url bar a bit.
Though don't worry... "ctrl-l un down enter" will still bring you to
http://www.bay12games.com/forum/index.php?action=unreadreplies if you're anything like me.
They just changed it so that the default useless thing that happens if you don't press down, is now a preselected item on the list.
Which, is so weird come to think of it. If I type un and press enter, it takes me to unknownworlds (or united.com on another computer). It assumes I'm typing an address from the beginning and helpfully autocompletes. That's... cool...
But the *list* below uses a different, far more useful search algorithm. The above is practically obsolete. If I want to go to NC State Employees Credit Union (ncsecu.org), I can type "credit" or "union" and press down. The autocomplete in the URL bar has no idea what I"m trying to do unless I start typing ncsecu instead. It's... not technically 100% useless, but practically.
But now they've taken that practically useless entry, which uses a completely different criteria, and made it visibly the first result in the list of useful results. I mean... WHAT? This thing is not like the others! It doesn't belong!
Again, I am thankful that the keypresses necessary haven't actually changed. It's just ugly and brings attention to the fact that it probably shouldn't even be there in the first place. And there's seemingly no way to fix it, yet... Hopefully the Classic Theme Restorer add-on will get an update soon.
Agh, why!?
