Hi, with version 152, the "send tab" is now limited to mobile Firefox. Please bring back to full feature that enables to share tabs across devices, irrelevant of mobile or not. I see that on mobile (Android), the "Share" feature still includes all the instances, there is no reason that it is removed from the desktop version.
I could definitely live with the possibility to manage whether a device should show up in the list of devices, but stop limiting it to mobile (or any other criteria). This is a showstopper for me, I use this multiple times a day, to send myself tabs from one device to the other (e.g. work laptop => home desktop, travel laptop => work laptop, etc.). This would make me switch to another browser.
BTW: having an icon in the toolbar for this feature (without the restriction) is a great idea.
