Comment on attachment 8935370 [details] Bug 1423891 - Panel header is gone when going back from Bookmarks to Library. https://reviewboard.mozilla.org/r/206266/#review211882 r=me with the below nit addressed. ::: browser/components/customizableui/PanelMultiView.jsm:497 (Diff revision 1) > + let reverse = !!aPreviousView; > + > viewNode.panelMultiView = this.node; Nit: seems like the definition of `reverse` could just come after setting `viewNode.panelMultiView`, right before the `if (!reverse)` and not insert an extra blank line (but maybe one before it if you think it's important to separate the assignment to `viewNode.panelMultiView` from the definition of `reverse` ?)
