How can you get CMD + L to open a new window, when all windows are closed?

Question

In Firefox 28 and earlier, you could hit Apple + L (CMD + L) when no FF windows were open, and it would pull up a blank page with the cursor blinking in the address bar.
After installing FF 29, when you hit CMD + L (with no windows open) it just plays the system alert sound and does nothing.
I want to be able to hit CMD + TAB to gain control of an idle Firefox, and then be able to hit CMD + L to gain control of a BLANK address bar.
Every other version of Firefox I've ever used did this, so am I missing something here? Any ideas?
Note: I realize that you can hit CMD + N to launch a new window and then CMD + L to select the text within the address bar. I'm not looking to re-train my habits within Firefox, but simply want that feature like it was in the previous 28 versions.

Answer 1

Well, after an entire week without a word from Mozilla, I officially give up.
I understand that new software will have bugs when it is released. I understand that the bugs are fixed in the order of greatest impact/priority. I also understand that my issue is not a bug, rather a feature that was inexplicably removed.
A couple of things I cannot understand —
Why would Mozilla remove '''ANY''' features from their software when they are touting this as the most customizable web browser ever? That is obviously not logical and will be to their detriment in the long run.
Furthermore, if a person did get on here just to complain about this update, they were immediately met with a canned response from a moderator, which offered a few options to make Firefox '''LOOK''' like the previous version. That speaks volumes about this update and the developers' confidence in it. The person who gets on here with a legitimate problem asking why a feature was removed — they get '''NO''' response from a moderator. Again, this speaks volumes. I am not even asking for an immediate solution to this problem, just the acknowledgement that there is a problem. On top of that, especially in the development of software, the old adage particularly rings its truest — ''If it ain't broke, don't fix it.''
Lastly, I think we can all agree that Firefox 29 is a blatant ripoff of Google Chrome. If I wanted Google Chrome, that is exactly what I would have downloaded. That pains me not only as a devout Firefox user for nearly 10 years, but especially as I have donated over $200 to the Mozilla Foundation in that time. In other words, I have financially supported the development of a software that has become absolutely indifferent to its users' needs, and moreover, they have now resorted to copying off of their neighbor.
I have since rolled back versions — all the way to Netscape Navigator 9 — which seems to have just about as much functionality as the bungled mess that is Firefox 29.
I genuinely appreciate all of the time and effort that goes in to creating open-source software, and I financially support the projects that I feel adhere to the open-source philosophy. That said, Mozilla.org seems to be straying away from this philosophy, to the point where, for me, it is simply time for a change.
Thanks for the memories, Firefox!
