[Feature Request] Drag and drop bookmarks from the BSP2 sidebar of one Firefox instance into the BSP2 sidebar of another Firefox instance

[halejok]

Hi,
I usually have multiple Firefox instances (not windows) running simultaneously (versions from portableapps.com).
Is it possible to implement drag and drop bookmarks from the BSP2 sidebar of one Firefox instance into the BSP2 sidebar of another Firefox instance?
Regards, hjok

Hello @halejok , indeed, right now this is failing because I am missing a firefox instance id to tell that a received drag&drop is coming from an exterior instance of Firefox, and not from our own instance.

I need to investigate if there is an easy way to detect that ..
