I know this is a screwball one so I hope I'm in the right section. Please bear with me while I give you the background so you don't think that I'm up to no good.
My cousin/business partner gave me his Facebook password about a year ago because I don't do Facebook but our business has an account and some sort of account where we get Google reviews and he wanted me to go in and look at them on occasion using his Facebook password because I wouldn't set one up. All has been good for the last year or so, I would just type f-a-c-e-b-o and then Firefox would automatically load his Facebook page. After a while I started following a friend of his who is an acquaintinance of mine also. Since they are friends I could see his timeline also.
About 2 weeks ago I did something that as soon as I did it I thought "Oh carp**, I've erased his password". Sure enough I did. So what I'm trying to do is get his password back if I can. I'm not trying to steal it or hack it because I already had it. I'm trying to get my laptop back to the point it was at before I overwrote the password and locked me out. I'm running the latest version of Firefox on Windows 10. Since the overwrite I have downloaded the latest version of Firefox and I also went in and set up a Facebook account. That gets me into the business side but not able to look at my friend's timeline because I'm not friends with him but my cousin is and that's why I'm trying to get his back. I tried to restore Windows to an earlier point but the rollback feature was not turned on.
I don't want to ask my cousin for his password again because he knows I set up my own Facebook account and will wonder why I now want his password and I don't want to tell him why. It will take way too long to explain why I want to follow my friend but don't want to be his friend on Facebook.
So I hope you can show me how to get my laptop back to the point it was before I screwed up the password and when I get there the password will be recovered. By the way, I also looked in my saved passwords in Firefox but it's not there so I don't know how Firefox was defaulting to my cousin's page to begin with.
