i do have a creative player and i did remove all of the programs that came with it. i still have the problem. i use norton internet security not norton 360. is there something in internet security that could be causing the problem. i don't use that on my dell laptop. it came with symantec endpoint protection. firefox on laptop works ok. thanks but still have problem

this didn't help. thanks

i just had some other problems with settings being save with cool previews so i decided to uninstall firefox. i then reinstalled firefox and everything seams ok. i can get another home page to stay saved and open when i start firefox. ope this helps someone else.
