interface is not refreshed while page is loaded

Binary package hint: firefox-3.0

It happens on some websites that the page you're loading isn't displayed properly since the interface isn't refreshed.
In such case you can still see the previous page or the background of your desktop in the Firefox interface.

You don't know the page is loaded except if you try to scroll in it then it looks like a "manual refresh"
