If I click on a site that uses those "services", I can forget about the page ever loading. If I pop open sysinternals, I can watch the Private Bytes History ratchet upward 1 - 2 Mb per second, yet the page never finishes loading. Eventually, the Private Bytes usage hits a breaking point, usually 350 - 500 Mb, and it drops down to around 200 and holds there. The CPU usage also spikes up to the upper 90's and stays there. I have started doing IP lookups of those DNS's and blocking them, but that doesn't always work. Reproducible: Always Steps to Reproduce: 1.Open website containing "quantserv" or "google-analytics" 2.Wait... wait... wait some more 3. Actual Results: Page never loads entirely, CPU usage stays in the upper 90's Expected Results: Page load.
As Emily Latella said, "Nevermind..." It was caused by an add-on. It was a small add-on, the first add-on I got way back when I first downloaded FF last year. I should have disabled it too when I was running through the diagnostic steps... [hangs head in shame]. It was "Extended Cookie Manager".
