When i format my pc i always backup my firefox profile, because with sync it doesn't save my extensions' data that i need. I always did it this way. So yesterday i formatted my drive cause windows was getting too slow and i had too much junk to try and clean it, so i backed up what i needed plus the firefox profile (which was working when i backed it up, i only use firefox and use it daily). I have 2 users on my pc, one for me and one for my dad so i backed up his firefox profile too. Today as i was going to reinstall everything i put my firefox profile on my win user and his profile on his user account. His profile works perfectly fine he has all his history from way back, password ect. but mine only loads the extensions i had installed not even with the data of any of them and that's it, i dont have my bookmarks, passwords,history...nothing... pls help me i'm desperate. Thanks so much to anyone that takes time to help me :D
