Yahoo asked me to download the new Firefox 4. During the process I did something that caused my system to say that Firefox is now not supported. I have OS X 10.4.11, I show a slash sign thru the Firefox icon on my Desktop and in my Firefox icon in the Applications Folder.

Are you using a Intel or PPC Mac ?

For PPC then see http://www.floodgap.com/software/tenfourfox/

Otherwise the last version from Mozilla that works on Mac OSX 10.4x is Firefox 3.6.* http://www.mozilla.com/en-US/firefox/all-older.html

Firefox4 does not work in your version of Mac. There is a third party version that is occasionally recommended.

Try OS X 10.4.11 in the Search Firefox Help box above for discussions, information and, maybe, the third party version.

Thanks so much for your help and the link. Back to normal. (At least for me) Saved me money and a trip and to the Apple Store

The newest Firefox doesn't work on Mac OS 10.4 you say?? I'll just have to keep using Safari. You suck Firefox. Goodbye.
