Reproducible: Always Steps to Reproduce: Create a file with the code <pre>asdf&#13;asdf</pre> in FF4 Actual Results: Text is shown as "asdfasdf" and when I copy it, there is written "asdf asdf" Expected Results: Shown and copied as "asdf asdf"

Workaround: Just use &#10; (breaks in any browser). This is a regression from Fx3.6 and a HTML5 parser issue and might be intended. "HTML5.parser.enable=false" gives the old behaviour. IE9, Opera 11.10, Fx3.6 break on &#13; Chrome 10 and Fx4 don't.
