This is probably in the completely wrong Product/Component, but here goes: Google Map Maker (http://www.google.com/mapmaker) lets you edit roads, places, etc., and yet editing broke in the 20120531 nightly of Firefox, which I determined with mozregression. Here is the pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=65fa5cb6f79c&tochange=3aa566994890 STR: 1. Open up Google Map Maker 2. Log in (if not already) 3. Zoom in all the way on the map, near roads 4. Use the Edit menu, and then select Select a Line 5. Select a road with your mouse 6. Click one of the red road bubbles, and then click "Edit" in the white tooltip that appears 7. Click "Edit this segment" Expected output: Options open up in the sidebar, allowing you to change attributes of the segment. This happens in 20120530. Actual output: Nothing happens when you click "Edit this segment."
