It's a known "bug" that actually came with Firefox 4.
It's basically that the browser keeps feeding you the cached page rather then to get the actual page.
In order to "fix" this you need to disable http caching.
Go To about
:config
(type it where you type in web addresses)
Then search for:
network.http.use-cache
And set it to False.
Now press (ctrl+)F5 or restart your browser and FireFox should be showing you pages AS THEY ARE.
(and not anymore as they were)
Hope this will end the endless repeating of this in the ChatBox.
