About an hour ago I did myself a huge disfavor and accidentally reset firefox, losing all my extensions, open tabs, and web history. However, I found my "old firefox data" and copied the information I needed onto my new profile (using the guide found here: https://support.mozilla.org/en-US/kb/Recovering%20important%20data%20from%20an%20old%20profile#w_copying-files-between-profile-folders). But now I don't know how to "save" my profile. Restarting firefox seems to do nothing, and I'm too scared to do anything else (lest I mess up AGAIN). Can anyone help me with this? Am I doing it incorrectly? EDIT: fixed the problem! If anyone is dumb like me and had the same issue, what I did was create an entirely new profile and copy all the files from the old profile into the new, and then restart firefox. Apparently I was just copying the file onto the same default profile, so it would just revert back after I closed the window. ._.
