We'll need some more information to be able to investigate. Can you describe the behavior you're seeing in more detail? Please provide detailed reproduction steps and/or screenshots of what you're seeing, if possible.

I think this bug is saying that Chrome appears to be taking information from sites that you have accessed and providing it to ad networks for the purpose of targeting. Please correct me if I have misunderstood the report.

That would be violation of the Chrome's security model, which is largely concerned with preventing information on one website from leaking to other sites, and is something that we take very seriously.

Depending on how and where you are seeing the ads, there are a number of ways that such information could be available for ad networks for targeting. For instance, if you visited sites providing information on a given condition, and that site embedded tracking pixels. This is possible due to the design of the web, and is not a flaw in your browser.

Closing due to lack of feedback. As #2 explains, this doesn't sound like a bug in the Chrome browser, but please feel free to provide more information if we're missing something. Thanks!

Sorry I wasn't able to get back.  What kenrb is saying is basically what I was reporting.  I'm not sure how to further troubleshoot the issue.  I used chrome to open my patient portal with my doctor's office.  I clicked around and looked at my reports (blood work, weight and such) and then, after logging out I started to see ads that were related to items in my report.

I don't really have a way to check to see if it's Baader-Meinhof Phenomenon, if it's extrapolating from other searches I've done (assuming I'm fat because I looked at a food video so it's sending me ads for bariatrics on sites) or if it's actually from a data leak.  The only thing I can add is that most of the ads I've seen have popped up on Youtube.  I submitted it as a chrome concern though because the records I was looking at were accessed on chrome.  The ads popping up seems to be occasional, so I can't reproduce it on demand.
