Firefox 42 附加组件兼容性

General

• Remove support for the prefixed mozRequestAnimationFrame.
• Convert newTab.xul to newTab.xhtml.
• Provide visual indicator as to which tab is causing sound. This required some changes to the tab XBL bindings, so it can break add-ons that change tab behavior or tab appearance.
• Badged button (like social buttons) causes havoc with overflow and panel menu. This was broken for a while, but it’s fixed now.
• Calling Map/Set/WeakMap() (without `new`) should throw.

XPCOM

• Split nsIContentPolicy::TYPE_SUBDOCUMENT into TYPE_FRAME and TYPE_IFRAME. This should only affect your add-on if it implements nsIContentPolicy.
• Use origin for nsIPermissionManager. Permissions in the Permission Manager used to be handled per-host, and now they will be handled per-origin. This means that https://mozilla.org and http://mozilla.org have different permission entries. This changes some methods in the Permission Manager so they accept URIs instead of strings.

New

• Create API for add-ons to add large header image to speed-dial home panels.  This API is available for add-ons on Firefox for Android.

Convert newTab.xul to newTab.xhtml  不知道是否会推广呢，抛弃掉xul。

Provide visual indicator as to which tab is causing sound.  是杀手级功能，可惜来的太晚了，根在Adobe，也在多进程。
