Windows 10: Want a Clean Install of Mozilla Firefox.

I am trying to do a "clean install" of Mozilla Firefox because it stopped working. It would not open properly.
A simple uninstall from Programs and Features then a Reinstall of Firefox did not fix the problem.

After an uninstall of Mozilla Firefox.
There are 2 folders that need to be deleted to do a "clean install".
One is located at C: > Users > david > AppData > Local > Mozilla (this one deleted without a problem).
Two is located at C: > Users > david > AppData > Roaming > Mozilla (which will not delete).
Trying to delete the second folder an error message appears. "Folder Access Denied You'll Need To Provide
Administrator Permission To Delete This Folder".
Clicking "continue" after the error message does nothing except the message reappears.

Here is the thing I can't understand. My computer has only one account and I am the Administrator.
I double checked that at - Control Panel > User Accounts > User Accounts.
Any Ideas? Suggestions? Advice? (Pics below - Admin & Bad Firefox)

Mozilla Firefox on Features Update Windows 10 version 1709?

Mozilla Maintenance Service has been a part of Mozilla Update Mechanism for a while now. Mozilla Firefox and Mozilla Maintenance are not a part of Windows 10 are not a part of Windows 10 though. So, you must have installed it without realizing.

But, I have both Mozilla Firefox and Mozilla Maintenance here in my Apps and Features. I installed Firefox a long time ago and its been a part of the upgrade mechanism ever since.

 

firefox issues after microsoft 10 upgrade

Hi Steve,

If you're having issues with Firefox after updating your operating system, we recommend that you perform a clean reinstall of the program. This process does not remove your Firefox profile data (such as bookmarks and passwords), since the information is
stored in a different location. To do a clean reinstall of Firefox, please follow these steps:

• Download the latest Desktop version of Firefox by visiting their official website and save the setup file to your computer.
• Completely remove the application from the system by accessing Programs and Features through control panel then select Firefox and uninstall the program.
• Delete the Firefox installation folder, which is located in one of these locations, by default:
  
  C:\Program Files\Mozilla Firefox
  
  C:\Program Files (x86)\Mozilla Firefox
• Proceed with the installation. Double-click the downloaded setup file and go through the steps of the installation wizard. Once the wizard is finished, choose to directly open Firefox after clicking the finish button.

Give us an update with the outcome.

 

Have a look at this......

Uninstall Firefox from your computer - Mozilla Support Community

 

Yes I saw that and it leads to the same problem. The problem with deleting the folder is a Microsoft problem.
Thanks for trying - the Mozilla link seems to state it is very easy to delete the 2 files.

 

Check your permissions for the Roaming\Firefox folder, here I have full access on it.

 

Looks like I have FULL CONTROL but 2 other accounts have full control also.

 

Typically when I have seen the pop up box, clicking on "CONTINUE" solves the problem.




It might be easier to just use a RESTORE POINT to reset my computer.
