I have received this message before, and used Task Manager to close the process. Then it would start OK.

This time, it won't start, and the same message is displayed.

Is plugin-container.exe listed in task manager? Did you try restarting your computer?

I tried ti repair Windows, to no avail. However, when I restored the computer to an earlier date, Firefox returned, running properly.

Thank you for your assistance.

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":
