When I upgraded to Firefox 4, it removed my CA internet security program as incompatible. How can I use it?

Firefox doesn't remove security programs, the most it does is to disable Firefox extensions installed by a security program that aren't labeled as compatible with the version of Firefox you are using. See the CA website or contact their support to see about getting an updated version of their Firefox extension/s that is compatible with Firefox 4.0.1.
