Hi! Is there a particular service that you are having issues with?

If you agree with this then follow these steps ----

We’ll cover 6 modern best practices for ensuring your login process is as effective as possible:

Let users see their password (if they want to). Notify users of suspicious behavior. Limit the number of password and username login attempts. Ditch modern password strength checkers. Update your modern password and username login standards. Eliminate the need for a new password and username.

My request is that please explain question clearly I am unable to understand that what you have to do

What I do is to place my fingers on the keyboard and randomly start pressing keys.
I then edit the string so that it is excepted by the password rules. (upper/lower/number/symbol)

I need a new password that works.

Are you having an issue with Sync?
Or with signing in to your Firefox Account?
