That sounds like a corrupted Browser issue. What and how did you update firefox? And what addons do you have and security software is installed?

Firefox updates automatically. No add-on's. Trend micro security. I have all this same stuff on my other computer running the same os widows 10 without the same problem.

Hi hroth7, Trend Micro's password manager disables the built-in Firefox one between sessions. If you don't use Trend Micro's password manager, you might be able to disable it (if it's part of a suite) or uninstall it (if it's a separate program in the Windows Control Panel).

Regarding Custom settings, Firefox will show that if anything listed under that section has been changed from the defaults. If you review that section and everything looks the way you want it, don't worry about the selector changing.

I uninstalled the Trend Micro password manager which I was not using anyway and all is working as inputted. Thanks for the tip. God Bless!
