864950 - Developer Tools lose state when tab is dragged to a new window

Status: RESOLVED DUPLICATE of bug 1618329

(DevTools :: Framework, defect)

Description

[Simon Sarris]

If you have at least two tabs open and open developer tools on one of them, then drag that tab away to create a second, separate Firefox window, the tab within the newly-created window loses at least some of its Developer Tools state.

Specifically, developer tools get closed (I think this is bad in its own right, Chrome does not do this) and all of the performance profiles in the Profiler get cleared.

I noticed this when attempting to visually inspect two tabs' performance profiles side by side, and moving the tab into its own new window destroyed the performance profiles!

This is a problem on at least Nightly 23.0a1 (2013-04-23) and also 21.0.

I assume we are reacting on a TabClose event or similar and destroy the toolbox. There must be some way to check if this is a tab-to-window drag and do the same thing we do when we detach the toolbox.
