Problem in Mozilla Browser

[othman El Moulat]

Hi guys;
i'm facing troubles with my Mozilla web browzer...it seems that it does
not communicate with the server... simple example:  i open the URL:
www.google.com  type in my search key words and validate : nothing
happen :-( 
it just gives nothing ! 
but the browzer works when i click a link in a web page...but when i
send a query to the server it just fails...
any ideas?

many thanks indeed...

othman.
