1. Put Firefox into full screen mode to make this bug even more striking.
2. Browse a broken link and thus trigger a message like

  File not found
          Iceweasel can't find the file at /usr/share/doc/HOWTO/Sound-HOWTO.html.

  Check the file name for capitalization or other typing errors.
  Check to see if the file was moved, renamed or deleted.

Note there is only one option "Try Again".

No Cancel.

Same for broken URLs.
