1634033 - Lazify customize mode, including customizemode-only panels and menupopups

Status: RESOLVED FIXED

(Firefox :: Toolbars and Customization, task, P2)

Description

[:Gijs (he/him)]

+++ This bug was initially created as a clone of Bug #1634031 +++

These are

<menupopup id="customizationPaletteItemContextMenu">
<menupopup id="customizationPanelContextMenu">
<panel id="downloads-button-autohide-panel">

They are only used from customize mode.

These should be reasonably straightforward to lazify, we can stick them all in 1 template and delazify them when customize mode opens.

Morphing this - in addition to the panels in comment #0, this include: https://searchfox.org/mozilla-central/rev/2bfe3415fb3a2fba9b1c694bc0b376365e086927/browser/base/content/browser.xhtml#1402

used to avoid doing any work for all the contents of customize mode by its hidden=true attribute. It should be possible to replace it with html:template opening/closing tags and update the code in CustomizeMode.jsm to de-lazify it instead of unhiding it.

We should probably do it all in one bug.
