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.
