I'm using Firefox 23.0 on Ubuntu 12.04 and encountered the following problem:

1. I navigate to http://www.openstreetmap.org and zoom into some area.
2. In the address bar I get a permalink, say this one: http://www.openstreetmap.org/#map=8/58.898/25.587
3. I switch to the traffic map and the link changes like this: http://www.openstreetmap.org/#map=8/58.898/25.587&layers=T
4. I remove the "&layers=T" part in the adress bar and hit Enter, thus reproducing the permalink I had there before.
5. I do not get to the previous view / Mapnik layer, but instead the traffic map stays and the "&layers=T" in the address bar reappears.

Alternative:
4. I change the "&layers=T" to "&layers=C" (permalink to the cycle map).
5. I do not get to the cycle map, but instead the traffic map stays. The "&layers=C" and the "&layers=T" in the address bar reappears as soon as I change the map area.

Expected behaviour: Entering a new permalink in the address bar should navigate to whatever that permalink describes.

Actual behaviour: Entering those permalinks has no effect and the changes in the address bar are reverted.
