Unable to update from Firefox version 5.0


I have tried everything to update to the latest version but when the option of continuing either as Admin. or user it extracts then doesn't do anything further. If I use the Admin and enter the correct password it shows that either the user name or password are incorrect. If I use the auto update feature it says the update failed and to be sure no other firefox is operating, close and try again.

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox and any leftover program files and then reinstall Firefox. Please follow these steps one by one:

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu) and confirm all upcoming messages.
  3. Now, uninstall Firefox by following the steps mentioned in the Uninstall Firefox article.

IMPORTANT: On Windows, the uninstaller has the option to remove your personal data and settings. Make sure that you do not check this option; otherwise all of your bookmarks, passwords, extensions, user customizations and other Firefox user profile data will be removed from your computer.

After uninstalling Firefox on Windows, delete the "Mozilla Firefox" program folder, located by default in one of these locations:

  • (On 32-bit Windows) C:\Program Files\Mozilla Firefox
  • (On 64-bit Windows) C:\Program Files (x86)\Mozilla Firefox
  1. Go to the Windows Start menu and click on "Computer".
  2. In the Explorer window that opens, double click Local Disk (C:) to open the C:\ drive.
  3. Find the "Program Files (x86)" folder or "Program Files" folder.
    • On 32-bit Windows, double-click the Program Files folder to open it.
    • On 64-bit Windows, you will see a "Program Files (x86)" folder AND a "Program Files" folder. Open the Program Files (x86) folder.
  4. Look for a Mozilla Firefox folder. If you find one, right-click it and select Delete and confirm that you want to move the folder to the Recycle Bin.

Now, go ahead and reinstall Firefox:

  1. Double-click the downloaded installation file and go through the steps of the installation wizard.
  2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to see if this helped you!

Thanks Timc I understand all the steps but I'll have to have all my wits about me before I start this task. The only question I have is the uninstall step having the option to save all the personal data. I do want to save this but with all the programs I've uninstalled I don't recall ever seeing this option. Can you provide a little more detail about this feature so I can be sure I won't delete this? Thanks! The rest is obvious. Deleting was the only option I came up with but I wasn't sure how to save the settings if Firefox is deleted.

Thanks again, I just found the uninstall article so you don't have to explain.

Great news! I thought I disabled Comodo firewall which I recalled blocked a site address that I wasn't familiar with and turned out to be the Firefox update site. I checked again and noticed that I didn't completely disable it and that was the problem! You have to be careful with Comodo as it can sometimes be too good at blocking things we need. Thanks again Tmic for your help!
