I have 2 FireFox Icons on my laptop. One is for "x64" system, and the 2nd for a "x86" system. I've seen you recommend a "x32" and a "x64" install for Windows 10. Which one do I uninstall, and how? Do I then need to install a "x32"?

There is a problem with that, it might uninstall both. and take everything. Are both showing the same bookmarks and saved other stuff ? If so then should save your profile in the 64bit one. https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data Then uninstall both Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved.
