This is the sort of clever UI design that should be in firefox already. Really improves a workflow involving bookmarking.

I used to have the problem that it would place a bookmark in the default folder when using another bookmarking extension (like QuickBookmarkHere), but since this extension can now bookmark to another folder through searching or right-clicking in a folder, it replaced the functionality of two of my other bookmarking extensions, and the problem therefore solved itself.

I read in the reviews that dragging a tab to bookmarks will still save it to the default folder, but I don't use that anyway.

So, in conclusion: great work, thanks a lot!

EDIT: I noticed the addon has been saving my bookmarks to the default folder when I used the "bookmark to" feature. So I now have dozens of bookmarks that were wrongly filed. This isn't such a problem by itself, but it's perhaps more problematic to notice that the addon just can't be completely counted on.

Plugin doesn't work well with restoring bookmark backups or importing bookmarks from a file. Every single of my 2000+ bookmarks now sits in a single folder, which I have set as default.

It seems that there are also issues with syncing too. So while I have fixed this issue on one computer manually (partially by disabling the plugin and restoring an old backup). Yet after syncing bookmarks to my second computer, I now have the same problem on my second computer! Although I have properly synced the "fixed" set of bookmarks from the first computer. Yet somehow this plugin thinks that all of my "fixed" bookmarks are "new" and thus places them in the same single default directory.

As per description of this plugin, it should not interfere with sync. But it seems it does.
