I tried to update my old Firefox with Version 4. Received message: You can not use this application Firefox.app with this version of Mac OS X. How do I get my old version back, or make version 4 to work for me?

Dear Mozilamarcia, Thanks for your help with my problem of having lost my older version of Firefox. I downloaded Ver. 3.6.16, which is probably the version I had before this incident happened. It even picked-up all my bookmarks. Thanks again, myfirefox101
