I am trying to create a master password on a new machine, but all I get when I hit enter is this message: "Unable to change Master Password".

Pretty much as per the question, when I try and set up a master password, the error message says "Unable to change Master Password". There isn't one to start with, so I'm just wanting to set one for the first time.

Did you copy any files from another computer to the profile folder on that new computer?

Do you already have saved passwords?

If you haven't then try to delete the key3.db file and possibly logins.json and signons.sqlite in the Firefox profile folder. Note that all saved passwords are lost when you delete these files.

You can use this button to go to the currently used Firefox profile folder:

Thanks, I've deleted the key3.db and logins.json files as suggested, couldn't find one called signons.sqlite. Still unable to create a master password. The computer is a new build with fresh install of Win 7.  :\
