I tried the steps listed, but they didn't help. But I received a message that my computer is inadequate for other versions of Firefox. I hope the Air Mac is adequate. Thank you all.

Hello profme, Firefox 16 (16.0.2 to be specific) is the last version of Firefox that works with your 10.5 mac with Intel possessor. For 10.6 and above you can use the latest firefox see: Firefox 35.0.1 System Requirements

thank you

Thank you for helping me. I started poking around in the utilities and realized that my Mac was indeed outdated. I'm sorry to leave it. It's at lest 5 years old and it never even hiccuped. You Mozilla-support volunteers are in a class of your own.

And thank you Philip. You folks are so prompt in your replies that my head spins. You are the wise men/women of Mozilla.

For an Intel Mac the best option would be to update to Mac OS X 10.6 or later to be able to use current Firefox releases.
