When going to a Stack Exchange user profile (
http://stackexchange.com/users/userID/username), and you click All Sites, it leads to
http://stackexchange.com/sites#. I see a trailing
# in the URL.
So, when I want to go back to the previous page, I need to click the back button twice. Why is that?
The same happens to the list/grid view for all sites: Here is the grid view URL:
http://stackexchange.com/sites?view=grid# (this also includes the trailing
#). The List view URL is
http://stackexchange.com/sites?view=list#traffic, and this one is.
This happens in Firefox and IE.
