I want to track the creation and removal of docshells from a top level content docshell. Is it possible ?
There are no built-in facilities for this right now, as far as I can tell. You could simply add something....
One option would be to watch window creation for things being added, I guess, and pagehide for things being removed. But going from a pagehide event to "what is being removed?" is not trivial..
To observe changes in windows, I add a load and unload event on the chromeEventHandler of the top level content docshell like [1].
Yeah, that won't work. pageshow/pagehide would at least fire consistently, but they represent _pages_, not docshells.
