Upgrade Problem
Every time you open Firefox, you will prompt old version bookmarks, history, and passwords, and you can't use them. Choose to opt out or create a new personal file. There are also prompts for the upgrade, and the downgrading version is unsuccessful pls help me

This can sometimes occur if two different versions of Firefox are installed and your desktop shortcut (or Taskbar button) starts one version while an external link starts the other one.
As a starting point for investigation, could you check whether you have one or both of these program folders:
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x86)\Mozilla Firefox
Before removing any program folder, if you have Microsoft Office installed, you may want to set your default browser to Edge to avoid Office experiencing default browser confusion.
Only one version installed,The update prompt will pop up automatically every time you open the program

The multiple installs would be related to messages saying that you downgraded Firefox and need to create a new profile.
For messages about available updates, what version are you currently running? You can confirm on the Troubleshooting Information page: Use the Troubleshooting Information page to help fix Firefox issues.
about firefox : 91.4.1esr Upgrades appear to be automatic, with no human intervention. And the upgrade pop-up window is also random, and there is an upgrade prompt to open the browser after updating the version.
I see why Firefox wants to update: the current releases are:
- Regular: 107.0.1
- Extended Support: 102.5.0esr
You can manually download your preferred version from the following page and run it to do an in-place upgrade. You may want to make a backup first in case there is something strange going on.
I don't think it's a good idea,usually upgrade lastest version can fix some issues and have new problem.

I don't understand your question. Did you update and then Firefox still wants to update again?
If you check the Troubleshooting Information page, what version and what "Update Channel" are listed?

we checked application which version installed in computer from control panel，No different version versions exist at the same time
All I can do is recommend you set the environment variable MOZ_ALLOW_DOWNGRADE system wide and you won't have this issue.
Without looking at your machines, I don't have any idea why you would be using a profile that was marked for an older version of Firefox.
