I can not open Firefox. I keep getting the message "Failed to read the configuration file. Please contact your system administrator." I have tried uninstalling Firefox and then reinstalling it but without success. What should I do?

Which Fx version? When you uninstalled Fx, did you reboot computer before reinstall? Also, check for / delete any leftover files in the Fx programs install folders, before reinstall?

Is your profile in the default location or custom location?

Have you tried creating a new, completely clean profile - to test (then make sure to select that profile to start Fx - from the Profile Manager)? (no addons or plugins installed).

Does the user acct (that Fx fails under) have access ("rights") to all locations - especially for Fx profiles location?
