sometimes when i'm using the internet, it's fine and it works, but later on, firefox will simply stop loading pages. it tries to load up the pages i want, and it just displays this message each time:
Server not found
Firefox can't find the server at uk.eurosport.yahoo.com. (example of a website)
* Check the address for typing errors such as
ww.example.com instead of
* If you are unable to load any pages, check your computer's network
* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
this would apply for all websites, EXCEPT for www.yahoomail.com. it just works normally, but all other websites just don't work at all, and just display this message. it's really irritating, because i don't even know when to expect this to happen. help would be REALLY appreciated.
