User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20171002181526 Steps to reproduce: Navigated to a page, opened the web console Actual results: The console seems to have taken a step backward from previous versions. It now just opens objects as a dropdown, similar to Chrome, which I find makes it much harder to scroll through and search object properties: https://i.imgur.com/RscCK0X.png Expected results: In Firefox 56 (and earlier), the console has this nice tabular view on the right side when viewing objects: https://i.imgur.com/8VI2lUn.png

Please be mindful when reporting bugs, what you call the worse is for many people the better (or it wouldn't have been done in the first place). It provides a nice way to see multiple expanded objects at the same time, something that we couldn't do previously. That being said, we also have a bug to enable putting an object in a sidebar (Bug 1380501), so you'd be able to re-enable the previous console behavior. We also have plans to bring back (a better) search, and have some ideas to have innovative UI for the ObjectInspector (for diffing for example). I'm duping this bug in favor of Bug 1380501
