I've noticed that some browsers can vary by 10-20ms as well.

Speedtest.net Namesco:

Firefox - 36ms
Chrome - 20ms
Opera - 18ms
IE10 - 16ms

Obviously these are difficult to be 100% sure on, because my ping's all over the place anyway.

Pinging the same server on the command line gives the following results:

Ping statistics for 85.233.160.167:
    Packets: Sent = 500, Received = 492, Lost = 8 (1% loss),
Approximate round trip times in milli-seconds:
    Minimum = 16ms, Maximum = 85ms, Average = 21ms

Edit: as for why, apart from natural variation, browser plugins can slow you down. FF also runs Flash in a sandbox, which I guess can add latency.
