I have been having issues with videos out of sync in YouTube I tried to do a fresh install to see if that would fix the issue. When I uninstalled it and reinstalled it I found all was the same as if I did not uninstall it. So, I uninstalled it again, and when I checked there were still folders in my registry that I had to delete. Why is this that should not be happening...

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

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And at least one folder in the profile of each user on the computer.

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

Firefox uses two locations for the Firefox profile folder. Location used for the main profile in "AppData\Roaming" that keeps your personal data.

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

Location used for the disk cache and other temporary files in "AppData\Local".

  • C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\

Good point, and I did go into those files and removed those folders, and still found things in registry strangely enough.

Run a registry scanner if you have one. After rebooting the computer.
