I just got a new computer and when downloading and signing in to firefox on my new computer it somehow brought over saved tabs from my dad's computer and not my old computer. It did not used to be like this on my old computer however I created a firefox account on my old computer hoping that if I did that and signed in on my new computer it would bring over my saved tabs and info. It did bring over my info but kept my dad's tabs as well. Is there a way to get rid of my dad's tabs on my new computer without deleting them from his computer as well? I also then created a new firefox profile in hopes that when I signed in to that one it would only bring my information but it just replicated the original profile, now I am hoping to delete that second profile but I am worried that will delete all of my information because when I go to delete it it says it will delete a bunch of my saved information. Is that information saved in my original profile so that if I delete the second profile I created it won't delete the data from the original profile (which is just the same information on both) as well? I can't seem to find anything to sign out of other than the new firefox account I just created, I was hoping to sign out of whatever I originally signed in with and try a different sign in but I can't even seem to find anywhere to sign out. I am not sure how I managed to do this, but any suggestions on how to fix it would be greatly appreciated. Thank you.
