"Using an older version of FF can corrupt bookmarks and browsing history already saved to an existing FF profile. To protect your information, create a new profile for this installation of FF." This message comes up everyday, sometimes more than once if I have to close and reopen FF. When I check my about FF, it shows the latest version installed. This started last week. Thanks Tim

Hi Tim, have you run any pre-release version of Firefox such as Beta, Developer Edition, or Nightly? Firefox 67 may be seeing evidence that one of those touched your main profile at some point in the past. If all the data files work normally, it's probably not a problem, but I'm not sure how to get rid of the message.

Have not used any of the above versions. Thank you for the answer which will be good for future information.

Can you post the content of compatibility.ini in the profile folder?

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
