I close Firefox, then reopen and all my menu settings are back to default, as well as my homepage option. I have tried uninstalling already and that did not fix the issue. In the personas menu login, I DO have the "remember me" box checked but it keeps signing me out.

Which security software (firewall, anti-virus) do you have?

Some security software has virtualization or sandbox features that may cause problems by protecting and restoring files in the Firefox profile folder.


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

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
