title: Where are configured the folders icons in Thunderbird?
body: <p>Something happened to my thunderbird profile: now every folder in the folder three pane on the left has the same standard yellow folder icon.</p>
  <p>I mean that the special icons for INBOX, Trash etc. are missing.</p>
  <p>I've tried to temporarily rename the profile folder, then restarting Thunderbird, now all the special icons are back again.</p>
  <p>So the problem appear to be in the profile folder.</p>
  <p>I don't want to delete my profile folder cause it contain all my emails.... :-(</p>
  <p>any idea?</p>
  <h1>Edit</h1>
  <p>I forget to mention the version of thunderbird I'm using: Earlybird v.22.0a2.</p>
  <p>As a side note, if I delete the profile and let thunderbird recreate a new one, all the special folders icons (INBOX, Sent Items, Trash etc) on he left pane tree are recreated and showing fine.
  But... as I've been asking in my original question, I would like to avoid recreating the whole mail archive, since I've tons of mails...</p>
  <h1>&gt;&gt;&gt; SOLVED! &lt;&lt;&lt;</h1>
  <p>Finally I was able to determine the offending plugin!
  It was Remove Duplicate Messages (Alternate) v0.3.7
  Disabling it and installing Remove Duplicate Messages (original) v0.1.13 from the following link: <a href="https://addons.mozilla.org/en-US/thunderbird/addon/remove-duplicate-messages/" rel="nofollow noreferrer">https://addons.mozilla.org/en-US/thunderbird/addon/remove-duplicate-messages/</a>
  solved the problem for me!</p>
