    <p>For things like that, start out with doing an automatic
      conversion using <a class="moz-txt-link-freetext" href="https://bgrins.github.io/xbl-analysis/converter/">https://bgrins.github.io/xbl-analysis/converter/</a></p>
    <p>This will get you maybe 80% of the way. Then you need to do code
      adjustments and have the Custom Element classes extend whatever
      equivalent Custom Element class replaced the parent binding (if
      any). <br>

        <p>Dear Magnus,</p>
        <p>well done to everyone involved!<br>

        <p>Now it would be fantastic if somebody could assist in
          migrating FiltaQuilla. This extension one has been heavily
          affected by this move. I would see at it's core about 75% of
          the code needs to be rewritten. I have seen a pattern in
          Thunderbird that uses the function
          MozXULElement.parseXULToFragment in order to overload / inject
          xml, but I am not very sure what is happening at all, and
          whether this is "ninja style" programming or the official way
          of replacing xbl in order to create (sometimes customized)
          controls in the filter conditions / actions dropdowns.</p>
        <p>If anyone is interested in helping, I made a new source tree

        <p>As you may know, for the past year the Thunderbird team has
          put a lot of work into migrating away from the Mozilla
          proprietary XBL technology, and as of today, I'm happy to
          announce we're now XBL free!<br>
        </p>
        <p>Thanks, and congrats to everybody who participated in this
          effort! Especially Khushil Mistry, Paul Morris, and Alessandro
          Castellani each converted many bindings. Also a big thanks to
          the mozilla-central de-XBL team whose background work made
          this possible.<br>
