my friend has an old eMac that's running Mac OS X 10.3
she has been having internet problems, especially with facebook, and paying her bills. On facebook, she can't comment on any status's or chat, and some sites like Metallica.com aren't working, they redirect her to some Verizon page. Neither firefox (which can't update any further due to operating system being too old) or safari make a difference, and facebook is even worse on safari.
I have tried running ClamXav for the system to look for viruses, but it didn't find any.
I am just not sure what to do here, is the operating system just getting too old?
This particular computer has at least 256MB of RAM, so I know it can't upgrade any further than OS X 10.4
Any help would be appreciated
