When we installed Firefox 4.0, found it is not compatible with Trend Micro. How can I go back to the older version of Firefox until Trend builds a compatible version??

On add-ons manager, I see that Trend Micro NSC Firefox Extention 6.5.0.1234 is not compatible with Firefox 4.0.1. I have contacted Trend and been told that their builders have not yet created a product that is compatible. I think this means that I should revert to an older version of Firefox until my internet security is updated. How do I do this? I'm clueless.  :) Or, is there a better solution?
