Sorry you need to go.

Open the computer's Programs and Features or Uninstaller

What Firefox version were you using.

If this is a very old version (before 73) then best is to update this version to ensure proper profile migration and prevent data loss.

Thank you both for trying to help! I apologize for being slow in responding.

To FredMcD: I'm aware of the standard Windows uninstall procedure, and I've often used it. My concern was that others trying to uninstall Firefox found a lot of things left behind, so 'dirty' uninstalls. In my experience, junk left behind is more common than not, even when using application-specific uninstallers. But I'll go ahead and use the usual Windows tool. I'm undecided about whether to go back and manually delete empty app folders and such.

To cor-ed: My Firefox version was/is 89.0.2. I always accepted updates, while they were offered.

I'm getting along well with MS Edge, so far. It did a slick import of my Firefox data, and that seems to have worked. So far, the only glitch I've found is that it's not following my Setting to dump internet cache on exit. But that isn't a big problem. Last time I looked, Chrome (which I try to avoid) doesn't even offer such a Setting.

Best regards, Ed S.

If you open the about:profiles page, so you can the folders where Firefox stores your data. A typical uninstall doesn't remove those, so I suggest making a note of them, or use these shortcuts:

%APPDATA%\Mozilla - data such as bookmarks, saved logins, and history

%LOCALAPPDATA%\Mozilla - temporary data such as cached web content
