that the arduino uses pins 9 to 13 to communicate with the ethernet shield, therefore those pins cannot be used as general I/O in your project.

Should be 10-13 unless they changed something recently.

just connect led to D5 To blink it on /off

worked well on chrome and firefox  .
no thing is impossible except that the state of your mind keeps it so...
