perhaps it might help if you look in the Programs and features (Setting - Apps, and, on the right) and see if you possibly have two entries of different versions there

Did that. Only one. My guess it the legit FF. I probably do some research on the registry, as I'd bet it's there somewhere.

Maybe if you unistll FF , you can then find the other and delete it manually. Easier enough to reinstall.

True, but there is only one FF on my system, in any of the customary folders, and I don't think the remaining one will show up after reomving the real FF. My guess is that it's a, phantom entry with no artifacts in my folder structure. I'll run a search of the registry first

I was able to replicate your issue by installing two versions of Firefox, so for starters open "Add/Remove Programs" and verify you don't have two versions installed. If you don't then it's most likely a registry key left over for the old version.

To locate the keys

• Click on Start
• Type regedit
• Expand the HKCR hive
• Scroll down to FireFoxHTML-

Each version of FireFox will produce a FireFoxHTML-####### and FireFoxURL-#####. If you're on the current version of FireFox (63.0.3) then the correct two keys will be HKEY_CLASSES_ROOT\FirefoxHTML-308046B0AF4A39CB and HKEY_CLASSES_ROOT\FirefoxURL-308046B0AF4A39CB you should be able to delete the other HTML/URL pairs.

Once removed you will need to close and re-launch System Settings

If I may impose with another question that's related, my issue now seems only partially solved. I'm running FF 63.0.3 on Win10x64. For a long time, I kept Firefox to set my default browser to Firefox in the Options menu. Lately, every time I open FF, I am advised that FF is not my default browser. Then, I set it to the default in Windows/Settings/Apps. But after I close FF and reopen it, I'm again prompted that FF is not the default browser. So I go through the process yet again. Could there be some Windows registry setting? I created second profile and copied the bookmarks, cert8/9

I solved the problem. It was with a Firefox shortcut that I placed on the Taskbar. The shortcut opened FF to my home page, my.yahoo.com. I found that. if I opened FF from a Taskbar shortcut that opened Google.com, the issue did not occur. I deleted the problem shortcut and created a new one that also opened FF to my.yahoo.com and the problem did not present or recur. Regardless, thanks very much for your help!
