It would be really nice if you could open any link you see on your phone in Firefox on another device using the share sheet in IOS or make it accessible via shortcuts so people could implement this or other setups. I know I would find the send tab to device feature much more useful since I usually want to use it when I'm not currently using a browser and I want to save it for later. (very similar to the feature with the arc browser and its mobile companion, however most of the backend work for this is already implemented!)
