If you need to create a new Firefox profile, learn how to recover your old Firefox data such as bookmarks, history and passwords.

A Firefox [[Profiles - Where Firefox stores your bookmarks, passwords and other user data|profile]] stores all of your important data, such as your bookmarks, history, cookies, and passwords. If you've lost your Firefox settings, bookmarks, or saved passwords after updating or reinstalling, you might still be able to recover them from an old profile. This article explains how to locate your old Firefox profile and copy important data into your current one. *To sync and share data among multiple profiles and devices, see [[How do I set up Sync on my computer?]] and [[How do I choose what information to sync on Firefox?]] *To switch to another profile to recover missing data and settings, see [[Recover user data missing after Firefox update]]. *To restore the windows and tabs you had open prior to an update, see [[Restore previous session - Configure when Firefox shows your most recent tabs and windows]]. *To learn how to restore bookmarks only, see [[Recover lost or missing Bookmarks]]. {note}'''Note:''' Because your preferences and extensions often cause problems, this article does not explain how to copy these between profiles. If you follow the steps in this article, you will have to reinstall your extensions and reconfigure your Firefox preferences.{/note} __TOC__ = Back up your current profile = Before starting it is recommended that you make a complete backup of your existing Firefox profile in case something goes wrong.

If you can't open a profile from within Firefox, see [[Profiles - Where Firefox stores your bookmarks, passwords and other user data#w_finding-your-profile-without-opening-firefox|Finding your profile without opening Firefox]].{/note} # Open the '''old''' Firefox profile folder containing the files you want to copy to a new profile.<br>If you are copying data from an ''Old Firefox Data'' folder created after you refreshed Firefox, simply open the old profile folder it contains; otherwise, if you can open Firefox using the old profile:[[Template:OpenProfileFolder]] # '''Now close Firefox completely'''. To do this: [[T:closeFirefox]] # [[T:contextmenu]] on a file you want to copy and choose {menu Copy}. # Open the '''new''' Firefox profile folder by following the same steps in step 1 above. Ensure the profile folder is for your new Firefox profile this time. # [[T:contextmenu]] inside the profile folder and choose {menu Paste{for mac} Item{/for}}. Repeat steps 3-5 for each file you wish to transfer files over to your new profile folder. While copying your personal data from an old Firefox profile to a new Firefox profile, it is possible that you could copy over the file that is causing the problem you are trying to get rid of! The more files you copy over, the greater the chance of this happening. It is therefore recommended that: * You copy over only the minimal amount of files that contain your most important data that you simply can't live without. * You copy over a few files at a time, and then check that the problem you are trying to get rid of hasn't returned. {for win} <!-- Links copied from the note here: https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data/revision/288257#w_finding-your-profile-without-opening-firefox --> {note}'''Note:''' By default, Windows hides the {filepath AppData} folder where Firefox stores your profile.
