Hi my firefox account keeps asking me to log in to sync. I think the cookie must be getting deleted. What is the name of the cookie used to save my log in for my firefox account. I already excluded accounts.firefox.com but im still getting logged out every time. Any suggestions. Thanks

Exempt your Firewall from blocking the site, Adblockers, exempt them also. If using : security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate which will cause you to get dumped. See their Support Forums for help.

This is all I have on Sync :

You can open about:sync-log via the location bar to see if there are recent error logs available. You can upload a recent log if the log is too big to put in a reply. https://pastebin.mozilla.org/

Expect several days for a answer as may have to contact a Supervisor as we do not have access to what is required.

Please let us know if this solved your issue or if need further assistance.

It is a token placed somewhere in Firefox Sync and we have no idea what it is called. If you are using ccleaner please have it stop looking in the program folder.

The chrome://FirefoxAccounts entry in the password manager stores the authentication data (kA and kB) in JSON format. The signedInUser.json file in the profile folder stores the sessionToken that is used once you have logged on successfully.

Note that if you use a master password then you need to enter the MP each time you start Firefox, but you should only have to do this once during a session.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
