Application Mime File Type Preferences

I'm stumped!

I've gone through the entire user preferences, application support files, and library files and still cannot locate which file is containing the settings for mime type application association with .php files.

I am having an issue with Firefox only downloading .php files instead of displaying them in the firefox browser. The .php files continue to be associated with the dreamweaver extension and icon and continue to to tell firefox to download instead of rendering.

I was so frustrated, I did a clean install onto another hard drive (OS X 10.3.9 drive 2)and was able to get firefox to work on the new system os. Again, I have trashed all the dreamweaver files, trashed all the firefox files and settings and even after doing a reinstall of firefox I continue to get the same issue on the older install 1 os x (10.3.9 drive 1). Drive 1 has all my precious files, years of settings and other data that I want to keep. I just want firefox to render .php pages off my local drive instead of trying to download them.

Can anyone help me find the file I need to trash to make this happen? What am I missing?

Thanks,
