[ubuntu-uk] Bizarre Firefox behaviour

[Sean Miller]

Since yesterday's Jaunty update Firefox appears to have lost its
history, "refresh" etc. buttons and only has the original domain in
the address bar (ie. if I go to http://sitea.com and click on links
within the address bar does not change, even if I go to other sites -
rather like framed content).

Anybody else had this?  If so, how do I resolve it?
