Look on your desktop. Do you see a folder called; Old Firefox?

Thanks Fred,

1. 1 there is no “Old Firefox” folder on the desktop.
2. 2 One of the links said this:

“Click the menu button , click help and select Troubleshooting Information. The Troubleshooting Information tab will open.” There is no Troubleshooting tab in my menu. As a matter of fact I can not even find a Help tab to go to About to find my version number. Help! I find that so many of the articlsd I find on Google refer to menus that do not match mine. Things were so nice when we had a Menu bar

1. 3 One of the links referred to an Exit button in the Menu bar. Again, no such button exists

So, I wake up in the monring to find that Mozilla has arbitrarily deleted my version of Firefox with all my bookmarks and preferences and substituted this new version with a menu that matches nothing you refer to or Google can find.

How can I get back to where I was? Or should I just give up on Firefox and go to Chrome?.

Hi, please go to the below URL and find your Profile and see if there is a 2nd one in the folder, it will be the oldest dated one.

From your description, I think your Firefox was corrupted.

Let’s do a full clean re-install;

Firefox; Extended Support Release {web link} ESR Notes System Requirements +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 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)

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.
