What Mac do you have, and how much RAM memory is installed? You can make sure about that by going to the Apple menu, then About This Mac. Is there a particular reason that you have chosen not to upgrade your operating system? You would be better served if you upgrade your OS X, as you will have a lot of other options. That solution that I posted, with the PPC version of a nice web browser, is designed for those that want, or need to stay with PPC versions. Those cannot be upgraded to any newer OS X version The usual reason is when using a PowerPC Mac, such as a G4 or G5 Mac. Sorry - I assumed that you had to stay with 10.5.8.
