After I updated Firefox, everytime I press a shortcut icon to go to a web page using Firefox (default browser), a window pops up stating "Windows cannot find 'http://www.example.com/' Make sure you typed the name correctly and then try again."
The pop up occurs no matter which shortcut I use. One thing that is funny, Firefox takes me to the web page anyway, but the windows popup remains. Once I have Firefox open, either to a web page or to my home page and I click on a shortcut, there is no error message. It opens another tab to that web page. If I just click on the Firefox icon, there is no error message. Firefox opens to my home page.
