I had this picture in my head that sqlite-manager by lazierthanthou was still available, but now looking into it seems like it has been abandoned for quite some time. My bad! But about this “new” add-on i do not know.
For command line use you can use the binaries like @abff08f4813c said, which can be found here or some gui program like for example DB Browser

EDIT: (for Firefox) If you can’t remember the date and want to know, you can get it by opening your firefoxes profile directory -> find places.sqlite -> open it with sqlite3 command line or with some gui software and execute this:

SELECT datetime(visit_date/1000000,'unixepoch') AS visit_date, url, title
FROM moz_places, moz_historyvisits
WHERE moz_places.id = moz_historyvisits.place_id AND url LIKE '%https://www.reddit.com/settings/data-request%';

EDIT: Added received date
