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
Yeah much happier here, feels like a new home

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
If you are using Firefox check my previous comments, should help you find the request date. Let me know if you use some other browser and i’ll get the method for you!
