Hello, Tab74

Firefox automatically creates backups of your bookmarks, which can be helpful if your bookmarks are lost or missing. To recover them, follow the instructions below.

1. Click the menu button , then click Bookmarks.
2. Scroll to the bottom and click Manage Bookmarks.
3. At the top of the Library window, click on Import and Backup and select Restore.
4. Click the date of the bookmark backup you want to recover.
5. In the new window that appears, click OK.

Your bookmarks from the selected date should now be restored.

For more information, see the Restore bookmarks from backup or move them to another computer article. For other solutions, see the Recover lost or missing Bookmarks article.

Did this fix your problems? Please report back to us!

Best wishes Brad

Hi, Tab

As this issue related back to your account / password, you will have to deal with our direct one-to-one support for Mozilla account (which is a different thing from peer to peer support forum like this one).

Please submit a new ticket from this page so our support agent can assist you further.

Hope this is ok, and wish you all the best Brad

Please ignore this reply, I missed part of the thread. Sorry.

Is there away i can get my browser history and data back ,i logged out of windows couldnt remember my password ,logged in with a new password and all my data is gone .....

Do you mean you had to create a new Microsoft account for your computer, or a new Mozilla account to Sync Firefox? Or both? Or a different account? Please describe the steps in more detail.
