In attempting to save a new set of tabs to open on start-up, when I click the 'options' , option, on the 'Tools' drop-down list, I get an error message "The address isn't valid

The URL is not valid and cannot be loaded.

   Web addresses are usually written like http://www.example.com/
   Make sure that you're using forward slashes (i.e. /)."

I've used this multiple times in the past. I have recently downloaded Windows 10. Not sure if this is the culprit...

Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox menu button/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
