A single device is being recongnized as two devices

When I open the browser with the start menu and/or from the pinned icon on my task bar it's being recognized as one device .... and any links opened from an app are recognized as another. I have to sign in separately to them in my sync and they are shown on my account page as two devices. Even though I am sitting at a single windows 10 PC, with a single user login, and no other physical devices connected to my sync. I have tried signing out of both and disconnecting them from the account page and starting over ... but the problem just persists! I am also getting security requests from other places (google, microsoft, ect) saying that a new device is being seen (when accessing them from firefox) and wanting me to allow it.

Does anyone have any idea how I can stop this weirdness?

Which folder has your personal data like bookmarks and login data? I assume that is the 'default' profile. Current Firefox releases prefer a xxxxxxxx.default-release, so maybe keep using this profile and transfer data from the xxxxxxxx.default to this profile.


You can copy files like these with Firefox closed to the current profile folder to recover specific data.

  • bookmarks and history: places.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 (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
    if you only have key3.db then make sure to remove an existing key4.db
  • cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
    if you only have cert8.db then make sure to remove an existing cert9.db
  • persdict.dat for words you added to the spelling 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)

You do not need to copy key3.db if you have key4.db, the same for cert8.db that you do not need.

I should also add that when checking both instances, they are both Firefox 68.0.1 (64-bit)

It is possible that you have two profile folders and a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.

Firefox 67 and later can use a dedicated profile for each of the Firefox update channels and will lock the profile, so it can only be used by Firefox in a specific installation folder. For Release versions this profile would be a xxxxxxxx.default-release profile, profiles used in older Firefox versions usually used a xxxxxxxx.default profile (a refresh adds a time stamp).

Yes, there is a 'default' and a 'default-release' folder .... should one of them be removed?

Ok that gives me some needed insight to understand what is happening, I will just keep the release profile and remove the other as all seems to be there and working ok. I really appreciate the reply cor-el.
