Cache Cleaner and internet systems help.?

ok. I have the CA computer security system that comes with anti- spam, anti- spyware, anti-virus, and firewall (with cache cleaner). I know that whenever I run the cache cleaner, it erases all the urls or websites visited in the url box only in internet explorer. However, it does not do this for my other internet program, Mozilla Firefox. How can I have the cache cleaner clean both? Also, are there any other internet systems out there that are good to use? Thanks. 10 Points for best answer.
