"Send to Device": select multiple (but not all) devices

[henrebotha]

Currently, I am actively using Firefox on 4 devices: my work laptop, 2 personal laptops, and my phone. I frequently want to send tabs from one device to one or more others. Suppose I want to send a tab from one personal laptop to my phone & my other personal laptop, but not my work laptop; I have to right-click the tab, click "Send to Device", click "Personal laptop 2", then right-click the tab again, click "Send to Device" again, click "Phone". That's 6 clicks total, of which 4 are in transient pop-up menus that are relatively easy to misclick. This gets very tiresome when I have to repeat this sequence every time I want to share a tab in this configuration.

I would like the flow to instead go something like this.

1. Right-click the tab and click "Send to Device".
2. A pop-up window opens, listing all my devices, with a check box next to each.
3. I click the check box for each device I want to send the tab to.
4. I click a "Submit" button.

This way, in one go, I send the tab to exactly the devices I want, and don't have to go one device at a time. And as a bonus, this pop-up window might for example remember which devices I'd selected last time, so if I'm repeatedly sending tabs to the same configuration of devices, the flow simplifies to something like right-click tab → "Send to Device" → press Enter.
