Firefox 4 is incompatible with OSX v10.4.11. I replaced the old Firefox and am left with nothing. What do I do?

After updating to Firefox 4 and replacing 3.6, I am left without the ability to use this browser. I cannot find an older version to download either. There needs to be a fix or a link to download 3.6. I've already seen that there are many others encountering this exact issue.
