772377 - URL bar doesn't handle non-predefined XML character entities

Status: NEW

(Firefox :: File Handling, defect)

Description

[Jens Mönig]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120614114901

Steps to reproduce:

Open a new window/tab with the following URL:

   data:text/xml,<say>hello&#xD;World</say>


Actual results:

Firefox complains about an unclosed token


Expected results:

Firefox should show an XML document, either omitting the escaped CR or displaying it as break, but it shouldn't give an error message.

This doesn't just occur with escaped CRs, but with any non-predefined XML character entity, and it's not restricted to text/xml data types. Perhaps even worse, If you open:

   data:text/plain,<say>hello&#xD;World</say>

everything behind the ampersand character is cut off.
