"Uninstalled Foxfire and reinstalled.... still open tabs"

It's because your profile folder is left even if you uninstall Firefox.

How to fix this-

1. Uninstall Firefox. 2. Delete the folders-

C:\Users\user_name\AppData\Local\Mozilla

C:\Users\user_name\AppData\Roaming\Mozilla

Where user_name is your username. To find your username, click the Start menu button, the username is shown in the top-right below the user picture.

3. Now install Firefox.
