Thank you!

Thank you!

The newest version you can run on a Intel Mac with OSX 10.5 is Firefox 16.0.2 which you appear to have?

So you want to use a even older and more vulnerable version of Firefox?

Firefox 17.0 to the current 48.0 has required OSX 10.6 at minimum to run.

Note Firefox 49.0 will require OSX 10.9 at minimum to run. https://support.mozilla.org/en-US/kb/firefox-osx

Thank you again. I did not know if there was another version that came after that would still work. Looks like that is not the case. Really appreciate your help. Thanks again.
