I haven't been able to bookmark a page using keyboard shortcut
command + D or star icon in the address bar for about a month.
At first, I assumed this shortcut might've been removed in upgrade to version 25.0.1, 26 or 27.0.1 but after going through their change log at
http://www.mozilla.org/en-US/firefox/releases/ I couldn't find any of that.
Is there a way to troubleshoot this without losing my existing bookmarks?
