bold text Hello,

        no more Firefox since yesterday :-(
        
        Strange Problem. Suddenly no link functioned (Sound "pupup") Firefox freezes :-( Close and ... Firefox 
        didn't start :-( Boot ... same reaction!
        
        Saving Firefox-Profile and deinstall/install with newest install from Mozilla! And what happened?
        
        Install creates "c:\program files\mozilla firefox", ignoring my system 64-bit!? No profile under 
       "c:\users\&user\appdata\roaming\mozilla"! Icon on desktop.
        
        How can I install Firefox again? Installing without virusscanner and firewall, all tested!
        
        In the moment on the way with Chrome ...
        
        All the best from Dortmund and stay healthy!

Let’s do a full clean re-install;

Note: Firefox comes in three 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.


Download Firefox For All languages And Systems {web link}

Firefox ESR; Extended Support Release {web link}

Beta, Developer, Nightly versions https://www.mozilla.org/en-US/firefox/channel/desktop/

Install Older Version Of Firefox {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.
