Currently if you want to see the split console you have to click the button or press ESC every time you open the devtools, on every page, even on the same page after you closed devtools and opened them again. Please remember the state of the toggle globally, like in firebug.5 votes

CSS frame-by-frame animation editor. I believe someone on devtools started this project (might have been Paul Rouget?) and I would love to see it resurrected.63 votes
Firebug has a nice console representation of both sides of an AJAX request, including activity indicators when the requst is still pending.

As far as I could read up on it's only doable via Firebug (https://getfirebug.com/wiki/index.php/Net_Panel#Timeline) by now. I would like to optimise Apps like so:1 vote
We’re working on this right now, please see this bug https://bugzilla.mozilla.org/show_bug.cgi?id=928571 A new profiler UI should be landing in Firefox 34.
Chrome provides this and while I don't use it all that often, it has proven to be handy on a few occasions.73 votes

It would be good to have a detailed database style display for offline storage (indexedDB, localStorage) and a detailed view on appcache content. It would also help to be able to disable appcache on the developer machine and enable it later without having to continuously change the manifest file72 votes
This is actually just started
The rule-view inspector panel allows editing declarations inside of rules that apply to the currently selected element, but does not allow to add new rules.
This would be useful.
There should be either a '+' button somewhere or a contextual menu option, or some other means to trigger the rule addition.
The rule should, by default, be given a selector that matches the currently selected element.
Coming up with a selector that matches the element may be tricky, but we do have a utility that does this iirc (getUniqueCssSelector or something like this).

I understand that the cd() console statement is coming in 30. I can appreciate the flexibility of that, but it sounds way more cumbersome than just having a drop-down that allows me to switch between all the frames in my active tab.6 votes
This is handy in the case that you want to see all of the nodes in your page.

As far as I am aware, one cannot customise the devtools functionality. It would be nice if this ability was made available (as it is for firebug and Chrome developer tools).8 votes
