1241147 - Page Info dialog broken when opened from the sidebar

Status: RESOLVED DUPLICATE of bug 1241892

(Firefox :: Page Info Window, defect)

Description

[Florian Quèze [:florian]]

When clicking "View Page Info" in the context menu of the sidebar, I get a JS error:
JavaScript error: chrome://browser/content/pageinfo/pageInfo.js, line 354: TypeError: window.opener.gBrowser is null

The line causing the error is:
let mm = window.opener.gBrowser.selectedBrowser.messageManager;
http://hg.mozilla.org/mozilla-central/rev/b32f21db299c#l5.131


Steps to reproduce:
1. Bookmark a page.
2. Bookmarks -> Show All Bookmark
3. Select the bookmark, and click on the down arrow at the bottom left of the bottom panel.
4. Check the "Load this bookmark in the sidebar" checkbox.
5. Load that bookmark. The page is loaded in a sidebar.
6. From the context menu of the sidebar, click "View Page Info".
