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 perform the above: 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 the file isn't there, you can try this: Open bookmarks > Show All Bookmarks > Import and Backup > Restore, and see if you have a backup there.
