Can you provide a link to your thread on https://support.mozilla.org/ so I can see what went wrong there?
If you need to extract your bookmarks from one of Firefox’s automatic backups to use in another browser, or in a new Firefox profile, this tool can create an HTML-format file that is cross-browser compatible:
Thanks for the screenshot.
Did you already try creating a new places.sqlite database as described in the corresponding article: https://support.mozilla.org/kb/fix-bookmarks-and-history-will-not-be-functional
I don’t know what other program would be touching places.sqlite. Maybe some software that clears history (or spies on your history)?
