First off I know this is off topic/WP but I figure there are a lot of FF users and maybe someone else has encountered this.
With three different downloads of the most current version of Firefox I had the same problem on all of them.
I could not change the default Fireox start page on any of them even though I made sure that that box was unchecked upon each install, I also uninsatlled/rebooted before subsequent installs.
Everytime I tried to change this Firefox default startpage thru tools etc. I got a saving preference error.
The one thing I did not try was about:config and reset the home page there.
Anyone encountered something similiar to this or is this an attempt of FF becoming more like MS and not allowing the reset of home page from their start page.
It works flawlessly on mine but only had this problem on my Mom' laptop
