Where are profiles and bookmarks and search history stored on my computer..

Maybe I can manually recover data, especially history and passwords.

Otherwise it's easier to just use Chrome

Firefox uses two locations in the hidden "AppData" location for the Firefox profile folder. One location in "AppData\Roaming" for personal data like bookmarks and logins and another location in "AppData\Local" for temporary files like the disk cache, so make sure to look in the correct location.

Primary location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>
  • ~/Library/Application Support/Firefox/Profiles/<profile>

Secondary location used for the disk cache and other temporary files (Local Directory on about:profiles).

  • C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>
  • ~/Library/Caches/Firefox/Profiles/<profile>

You can use the button in "Help -> More Troubleshooting Information" (about:support) to go to the current Firefox profile folder or use the about:profiles page (Root directory).


You can copy certain files with Firefox closed from one profile folder to another/current profile folder to transfer/recover/backup your personal data. Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.
