Hi, some web site no longer support Safari 5.1 is there an upgrade I can get or use?

You need to upgrade the computer's OS or switch browsers. If desired, open the Mac App Store and try downloading Mavericks. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.

Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

Safari 5.1 is the most up to date version that runs on Snow Leopard. You would need to upgrade to Lion, or Mountain Lion, or Mavericks to get a later version of Safari to run.
