Why must FF 65.0.1 run as Administrator to prevent APPCRASH in ntdll when closing FF?

The only way I can prevent the following event is to run FF 65.0.1. (W7-64) as an Administrator. Is there any way around this? My other computers running FF 65.0.1 under W7-64are running fine. UAC says that FF does not require elevation.

I've tried restoring FF, disabling all the extensions, running in safe mode, all to no end.

If it's a clean install that's required, can I accomplish that and still preserve bookmarks, profiles, etc?

Clean install is backup bookmarks and then uninstall all firefox and deleting mozilla folder. This will insure a clean install.

Thank you for your response.

I understand what I must do to perform a clean install. The question remains, is the only solution to perform a clean install given what I have done so far?

Once it's corrupted any installs will not fix the problems.

Firefox comes in two or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.


Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

Sorry, don't understand what you're trying to say.

A file can be corrupted because of many reasons. When this happens, programs using that file get confused. And if the file happens to be a program . . . .

Normal uninstalls may not remove the corrupt files, therefor the file must be removed manually.

Note that some programs can detect such things and alert the user.
