Spinning this out from a discussion with Honza: https://searchfox.org/mozilla-central/source/devtools/client/framework/toolbox-process-window.xul - I believe this is doable. We can port the <commandset> in it and the toolbox-window to just hook up key shortcuts directly, and I'd also need to look more closely at mainPopupSet but AFAICT that's unused now. - We can probably also remove a number of the scripts loaded at the top. - We could either `hg mv toolbox-process-window.xul toolbox-process-window.xhtml` and then keep default ns as XUL, as we do with browser.xhtml, or porting most of the markup to HTML and keeping XUL only as needed. - We may consider porting the XULStore data from the old path the to new (so size/location info stays persisted).

Thanks for the report Brian, let's try to remove a bit more XUL! I am attaching first try for review. The module would deserve some code cleanup, but we can do it after... Honza

Ah, also, we might want to try to remove some of the scripts. Honza
