Great, a one click add bookmark (or delete), even though it's adding to the default bookmark list of choice only. And I like the recently added option to save either to the top or the bottom the default bookmark list. Wish this extension would somehow add the' add bookmark here' function to it's already very capable features.

I understand that any 'add bookmark here' needs 2 clicks, and FF 56 will not support the way ABH2 does the trick. What about a right click on a folder of the bookmark toolbar handled by the Default Bookmark Folder add-on? Could an add bookmark show up in that right click context menu, that sets new default folder to the folder clicked on, and stores a bookmark that to that new default folder?
