(Whiteboard: [Fixed by bug 1439697])

Reproducible on:
* 31.8 ESR Build 1 (20150624141335)
* 39.0 RC Build 4 (20150624153222)
* Aurora 40.0a2 (2015-06-24)
* Nightly 41.0a1 (2015-06-24)

Steps to reproduce:
1. Launch Firefox.
2. Enable the Bookmarks Toolbar.
3. Open a random website that's currently _not_ bookmarked.
4. Drag and drop its URL onto the Bookmarks Toolbar.
5. Check the Browser Console for js errors.

Expected result:
There are no issues nor errors encountered for this action.

Actual result:
controller.js:1621 throws the following error in the Browser Console:
> Tried to move an unmovable Places node, reverting to a copy operation.

Additional notes:
* This is _not_ a recent regression, as I've managed to track it back to Firefox 30.0 (20140605174243) so far. I'll follow up with a detailed regression range as soon as possible.

Just saw this occurring in 54.0.1.

Generally there's no harm in this error - it is just a warning for developers. It will, however, occur every time when dragging some text like URL test onto the toolbar as per comment 0 (and maybe the same for into the library window). There's no harm in it though.
