This seems to be drag & drop related, some comments from the crashes:

Was dragging a new bookmark into a folder and firefox crashed outa nowhere

Tried to separate one tab from the rest when it crashed.

I was just trying to drag my imported bookmarks around

crashed dragging a URL (via the lock icon) to a bookmark toolbar folder to add a bookmark

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
