Hi,

If use Windows Os once delete this way after uninstall C:\Users\username\AppData\Local\Mozilla

Or you can use CCleaner

After, again install

You can check if you can start Firefox in Safe Mode by holding down the Shift/Options key.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

See:

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.
