Quick note to Vista users, and XP users (I know there are still some of you using XP out there).
The last version of Internet Explorer that is possible to use on XP is version 8. A lot of websites don’t even support it anymore. It’s slow, old, not secure.
The last version of Internet Explorer that is possible to use on Vista is version 9. 9 is still more widely supported, but like 8, it is old and slow.
You are much better off using Chrome or possibly Safari. Firefox is an option, but as time has progressed, Firefox has turned into a pretty bloated browser, and is not very fast anymore. I can’t recommend it at this time.
