Thanks for your response. The actual problem is that I can't backup my profile to be able to use with a new account since the only device connected with the current account is an Android phone. I have root access and have tried to backup profile but I'm not sure I can use it with a new account. Could you provide more information regarding backing up profile data in Firefox for Android.

TIA

Backing up the profile isn't like a Windows computer you can find and backup unfortunately Android is pretty tough on this front. And since you can't access the Primary email that was the login there nothing more that can be done because without account. Also one should un-sync all devices to so that there is no sync issue from other devices if your re-syncing to get everything to connect. The info on profile backup would seem to indicate you need to go to android forum for help here.
