Hi, first try restarting Firefox: 3-bar menu > Exit. It's possible that Firefox may have created a new empty Profile. To select your original one with all your data, please see [[Recover user data missing after Firefox update]]. ----------------------------------------------------------------------------------------------------- In case a Refresh has occurred, please look on your Desktop for a file named Old Firefox Data - [[Refresh Firefox - reset add-ons and settings]]. *[[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]. *[[Recovering important data from an old profile]]. * Steps to recover data from the Old Firefox Data folder: With Firefox closed, open the Old Firefox Data folder on your Desktop, then highlight everything in it to select all the data and right click > Copy. Now press the Windows key + R to open Run, then type '''%appdata%''' in the box and click OK. Next navigate to Mozilla > Firefox > Profiles, by opening each folder in turn (your profile folder will be 8 letters and numbers followed by '''.default''') Finally, open that folder and right click > Paste - if asked, select that you want to overwrite the data. You can now close everything and start Firefox. ''If your question is resolved by this or another answer, please help other users by marking the best reply as Solved. Thank you!''
