Diễn đàn hỗ trợ Firefox

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew

I'm not sure if this is a FireFox issue or a google glitch, but here goes. Please give me direction on how to correct the above mentioned problems.

Thanks in advance for your time.
