Sending the tab to the desktop Firefox via sync instead of keeping it open actually perfectly fits your use-case. Seeing as that’s exactly what you’re doing, only manually.
things (and tabs) I do on a laptop are entirely different then the ones on the phone.
Nothing changes from normal usage when tab syncing is enabled, except that the list of tabs opened on the phone is available in a special tab on the desktop, and vice versa. Only explicitly sent tabs are opened on the other device.
