Created attachment 592519 [details] [diff] [review] v1 There is one line change in inspector.jsm. I moved "this.highlighter.highlight();" before sending the OPENED notification, because when switching tabs, Tilt needs to call "this.highlighter.hide();". If this hide() call is made before the highlight() action, it won't have any effect because line 293 in highlighter.jsm: "if (this.hidden) return;". This means that the "hidden" flag isn't updated to false when the OPENED observer in Tilt calls hide(), which makes the highlighter always show above Tilt when switching tabs. This behavior wasn't present before because I was setting the actual highlighter-container display to "none", a state which isn't modified by the highlighter internally.
