You could install the portable version of FF 3.6.

Thanks. I was unaware of a portable version. Seeing how it's still newer than a 4.0, I'm not sure if it would work or still have the same hiccups the updated full version has. There are verification issues and html vs. plain text issues between dotster and the latest Firefox versions. Dotster said it has to be 4.0 or older. If I find a secure site to download an old version, can download it without it affecting my current version? Can I have them both running without them affecting each other? I'm wondering why Firefox is not taking care of the problem (informed by dotster that they're still waiting on Firefox for a fix).

See this article about how to install multiple versions on Mac OS X (applies to any Firefox version):

Thank you both for your response. Both good advice. Thinking I will switch from Dotster to a better hosting site. Not happy with them and they don't work well with Safari, Google Chrome, or Firefox versions above 4.0. What a drag.
