Moving Firefox & Thunderbird to different HD

more options

I need to move Firefox & Thunderbird from the hard drive with the operating system to the other hard drive. The hard drive is almost full & need the room. Do I just move the folders to the other HD or... I just want to make sure that I do it right without losing anything. Thanks for any help with this, Dave

You can do a custom install of Firefox and Thunderbird on the second hard drive.

For Thunderbird this should work in a similar way.

You will have to use the Profile Manager to create a new profile on that new drive using "Choose Folder" (you need to create a new folder to be used for the profile beforehand) and transfer your personal data from the system drive to the new drive to ensure proper operation.


You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder.

  • bookmarks and history: places.sqlite
  • favicons: favicons.sqlite
  • bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
  • cookies.sqlite for the Cookies
  • formhistory.sqlite for saved autocomplete Form Data
  • logins.json (encrypted logins;32+) and key4.db (decryption key;58+) for Passwords saved in the Password Manager
    key3.db support ended in 73+; to use key3.db in 58-72, make sure to remove key4.db
  • cert9.db (58+) for (intermediate) certificates stored in the Certificate Manager
  • persdict.dat for words added to the spell checker dictionary
  • permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
  • sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)
