Not finding a lot of Firefox files

MemoryEmblem

When uninstalling Firefox it seems to miss out on a ton of files.
The only files it lists are

C:\Program files\Mozilla firefox\
C:\Program files\Mozilla firefox\Firefox.exe
C:\Program files\Mozilla firefox\Uninstall\Helper.exe
C:\Users\All users\Microsoft\Windows\Start menu\Programs\Firefox privat surfning.lnk
C:\Users\All users\Microsoft\Windows\Start menu\Programs\Firefox.lnk
C:\Users\Public\Desktop\Firefox.lnk
C:\Windows\Prefetch\Firefox installer (1).exe-bc01d5cf.pf
C:\Windows\Prefetch\Firefox installer.exe-174b108d.pf
C:\Windows\Prefetch\Firefox.exe-66015fd1.pf

The files it didn't find seem to be in appdata (that I know of anyway, was trying to delete places.sqlite)

Is this a normal installation of Firefox, that is, you downloaded the setup file from https://www.mozilla.org/en-US/firefox/all/#product-desktop-release?

Also, are you also selecting for uninstallation the Mozilla Maintenance Service app that is installed when you install Firefox?

Lastly, what version of Windows and what version of Uninstalr is this?

Yes

jv16 are you also selecting for uninstallation the Mozilla Maintenance Service app

I'm on a new pc now, I would have to plug in the old one again to check -- however: No I didn't uninstall a 'mozilla maintenance service', though I don't recall if it was in the list. But I know I didn't click one specifically at least.

jv16 what version of Windows

jv16 what version of Uninstalr

2.5

I got the old pc and checked;

For Firefox, the only files listed are the ones I listed above.

For Mozilla Maintenance Service the files listed are

C:\Program files (x86)\Mozilla maintenance service\
C:\Program files (x86)\Mozilla maintenance service\Uninstall.exe
C:\Windows\Prefetch\Maintenanceservice.exe-9596e406.pf
C:\Windows\Prefetch\Maintenanceservice_installer.-47a82ba7.pf
C:\Windows\Prefetch\Maintenanceservice_tmp.exe-6a746806.pf

So it doesn't appear that it would have found the files anyway. (Had to delete places.sqlite or something like that to remove all the empty unused bookmark tags)

My best guess is that the issue was caused because both apps were not uninstalled at the same time. Quite often, it's impossible to know for sure whether some path is relating to Firefox or to the Mozilla Maintenance Service and as such, it might be left behind if you don't uninstall these two at the same time.

If you have the time, you could re-install Firefox and then try what happens if you try to uninstall both Firefox and Mozilla Maintenance service app at the same time.
