Hi PlanetPrisoner , try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) and then see if that helps to download and install firefox from the next link (full installer) :

Most often, issues like that are caused by a firewall or/and security software which doesn't recognize new Firefox (and for that blocks the new firefox version). You have to remove all program rules for firefox from your firewall and let it detect the new version of the browser again.{In windows safe mode with networking, security software is disable}


thank you

I also turned all virus / firewall off. this is really weird, as I have always, 12 years, been able to work easily with removing and installing Firefox...?? I'll work more on the issue after around 7pm CST. THNX for input.
