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?

Here is the system requirements page: http://www.mozilla.com/en-US/firefox/system-requirements.html.

http://www.mozilla.com/en-US/firefox/all-older has the latest 3.6.x version, and http://www.floodgap.com/software/tenfourfox/ is another option.

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
