Hello, I have been getting this error across the board, on my personal computer and work computer when using Firefox. I've tried everything I've seen that was supposed to be a fix but it still breaks after a day or two and we have multiple clients complaints on the issue too. "Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox." I have tried: -uninstalling/reinstalling newest version of Firefox -using run, firefox -p to open the profile -creating a new profile altogether -setting my default profile Please let me know if there is something else we can try or a fix out there I haven't found.
