Sorry for the inconvenience. Known Navigation header breakage, its being "rebuilt" but forward nav should be ok now.
There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.

How long the installation takes depends upon the speed of your hardware, the installation type you selected, and the number of components to be installed. A typical installation takes between 20 and 40 minutes.
