Re: Dump frame tree in real time

Thanks. I'm aware that it's a privileged API. It seemed Botond was offering a workaround. Anyhow, because of all your help I was able to dump the Frame Tree (not in real time). But I also learned the frame tree doesn't contain all the information I need. Especially the z-order information.

Hi Botond thanks for replying, I just checked and calling drawWindow() doesn't output the entire page in the display-list dumps. It's as if this operation doesn't trigger the same things a regular render operation does. But your reply got me thinking. If I can force Firefox to always render

Re: Dump frame tree in real time

Great to hear you got this working! I'll carefully follow your steps and see if I can get it to work too. The downside of this approach seems that I can't easily filter out the dumps of the entire page. I'm only interested in the dumps from the whole page, not the ones from the viewport. But

Re: Dump frame tree in real time

Unfortunately Dump -> Frames using the Layout Debugger doesn't give me the information I'm looking for. I would like to access the following information about all visible DOM nodes (nodes that take up space in the document): - z-order - position - dimensions The Frame Dump doesn't contain any

Hi Daniel, Thanks for the info. Thanks to your instructions I was able to find the Layout Debugger Jeff mentioned. I forgot to add that I did add the debug option in .mozconfig when building the nightly. This was the full .mozconfig file # Define where build files should go. This places them

Check out https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/Layout_Debugger. I expect it gets the information that you're looking for. -Jeff On Fri, Apr 8, 2016 at 1:38 PM, Jip de Beer wrote: > Hi all, > > I would like to inspect the Frame Tree (or Render Tree:

Dump frame tree in real time

Hi all, I would like to inspect the Frame Tree (or Render Tree: http://www.html5rocks.com/en/tutorials/internals/howbrowserswork/#Render_tree_construction) in real time while browsing with Firefox. I first tried to access this tree with JavaScript or a browser addon. It seems that this
