Hi

If you have used the "forgotten password" route when your data was being synced, that data will be deleted. Do you still have the data on your other copy of Firefox?

No I don’t have any copy because I was not heard about the forget password can do that any one can help from your side to recover my data ? [Email address] is my gmail

Hi

I have removed your email address from your question for your privacy and security as this is an open forum.

I am sorry but we are unable to recover your data.

that's a shame i am leaving Firefox after 4 years of using after losing all my 4 years data by a simple forget password

Thank you for your feedback.
