I downloaded and installed Firefox 4, but it won't open. I have used an older version of Firfox for a long time. I now have nothing. What gives?

I've used an older version (3.?) of Firefox for a long time. I had loads of bookmarks. I downloaded the new Firefox 4. It won't open and the older version is now gone. I use a Mac with a 400 MHz PowerPC G4 with 1.12 GB SDRAM and a 60 GB Internal Hard Drive. I'm running Mac OS X Version 10.4.11. I really need to recover the older version of Firefox or make the new version work.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
