Yes one reason why we each may have a different result with the same web site is that our baggage of tracking ads and related scripts is unique to where we have been on the web.
I have used Ghostery on Firefox for the past year, puts an end to tracking ads. At times I have to disable the blocking (easy to do) or whitelist a site (also easy) in order to get a desired script to work, such as a bank log in.
Anyway life is much better without all the tracking ads.
