Broken XML rendering in Firefox

[SpecLad]

Create an XML file with <root>Test</root> as the contents and open it in Firefox. When Privacy Badger is enabled, Firefox just shows the word "Test" instead of rendering the entire contents of the file.

Thank you! The fix should be to do some kind of check for XML (like this one in uBlock Origin) in (some? all?) of our content scripts. Why does this happen in Firefox and not Chrome though?

It could be happening in Chrome, for all I know. I'm not a Chrome user, so I don't know.
