[SOLVED] Why is my XML file not rendered properly in Firefox?

Why is my XML file not rendered properly in Firefox?

I am using Firefox to read XML files, but it is not rendering the XML file properly. What could be the problem? I’m posting the XML sample below:

<?xml version="1.0" encoding="utf-8"?>
<ExtPostTransaction>
    <TransactionInfo>
        <UserID>us</UserID>
        <Password>pwd</Password>
        <ServiceCode>1010</ServiceCode>
        <TransactionID>T20120518091833</TransactionID>
    </TransactionInfo>
</ExtPostTransaction>

My Firefox shows it as:

uspwd1010T20120518091833

I am expecting this:

<ExtPostTransaction>
  <TransactionInfo>
    <UserID>us</UserID>
    <Password>pwd</Password>
    <ServiceCode>1010</ServiceCode>
    <TransactionID>T20120518091833</TransactionID>
  </TransactionInfo>
</ExtPostTransaction>

Solution

Finally found the solution for me. When Firebug is enabled it seems Firefox renders the XML file wrongly. When it is off, XML files are rendered properly.
