That would be something you would have to log onto their site and change your preferences at their site if you want to use different notification email.

I had a service provider in Montreal Quebec citenet.net , My firefoxe account was with them , I would like to move my account using my google email on an other internet service provider in ste-Marguerite du Lac Masson Quebec how can I do that ?

What internet service connection you are using does not matter. It is the email address you are using. https://support.mozilla.org/en-US/kb/change-primary-email-address-firefox-accounts

If you are using the same @gmail.com address then you should be fine.

If you still have access to that old email account then you can add a secondary email address and make that the primary email address. If you no longer have access to that account then you will have to create a new Firefox account.

You can add a second email address and confirm this address. Once it has been confirmed, you can make the second email address your primary email address.
