What's your computer system and Firefox version?
Let’s do a full clean re-install;
Download Firefox For All languages And Systems {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)
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 the profiles folder.
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.

Windows 10. I'm not able to open Firefox so I can't tell you what version I have.
I deleted all files re: mozilla, then I cleaned up anything relating to Mozilla in the registry (regedit) reinstalled Firefox, same error.
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
Start your Computer in safe mode with network support. Then start Firefox. Try Safe websites. Is the problem still there?

I thought that by using "Run" and typing the %appdata% link, it would take me to the hidden files where I then didn't see any Mozilla files. Then it hit me. I showed hidden, files, found the Profile folder, opened and deleted the parent.lock file and that worked!
Thanks for the link and the answer!
