Firefox is an internet browser. Firefox natively doesn't handle file transfers between devices, but there are various websites and cloud storage platforms that could do it for you.

For example, a common one for Apple products is iCloud. If you put files from the phone onto iCloud, you should download them from the iCloud website in Firefox on your Windows laptop.

Hope this helps.
