jscher2000 Jul 28, 2020, 5:12:26 AM By the way, I think there is some other difference between these two 64-bit Firefoxes. Maybe they are different "languages" or "locales"? At the bottom of the Troubleshooting Information page, there is a section on that. The one you don't want is, I think the U.S. English build. Is the other one a different language/locale? I did the first part of making IE 11 the default browser and renaming the Mozilla Firefox Folder. All that worked fine. The taskbar icon works. But, I went out of order. I did the above before I saw your "by the way" message. I am again attaching jpegs from both troubleshooting pages on the Internationalization & Localization section If this is what you are referring to they are both the same. So, if this is alright I will go back and redo the first part of making IE 11 the default browser and so on. Then delete C:\Program Files\Mozilla Firefox and the desktop icon. Anything else that needs deleting? Just for grins I am also attaching a jpeg of the Mozilla Firefox program from the Control Panel - Programs_Features page. Think that's it. Thanks again and again for all your help, Irv
