Steps to reproduce: 1) launch mozilla 2) double click on a bookmark in the bookmarks panel in the sidebar. The following error appears in the console: JavaScript Error: TypeError: top.OpenBookmarkURL is not a function URL: chrome://bookmarks/content/bm-panel.js LineNo: 37 Platform: Linux Builds 2000021309 and 2000021416 fail. Build 2000020415 works (I did not keep other builds in between, so I can't narrow down the problem to a particular build). Additional details: I compared the XUL and JS code between 2000020415 and 2000021309 but could not find the cause. OpenBookmarkURL() is defined in navigator.js. Maybe it's not visible from bm-panel.js? Or should it be called differently than through "top"? (I tried top.window.OpenBookmarkURL() without success)
