When I visited a page with an applet it froze firefox. I looked in the logs and saw this:
Aug 11 15:13:55 soncomputer kernel: audit(1155323634.469:38): avc: denied { execmem } for pid=3198 comm="gappletviewer" scontext=user_u:system_r:unconfined_t:s0 tcontext=user_u:system_r:unconfined_t:s0 tclass=process
What component does this fall under? Should it be selinux?
Yes. Please file a bug report against SELinux. GCJ applet viewer probably should be fixed in the future to not require execmem permissions but meanwhile the SELinux targeted policy can be modified to allow this.
You can do setsebool -P allow_execmom=1 and see if you are able to workaround this for now.
