Carlos: this might be a good one to look at if you run out of things to do. :) https://cs.chromium.org/chromium/src/chrome/browser/ui/page_info/page_info.cc?type=cs&l=845 looks like where we get the cookie count -- from glancing at the code, I'm guessing it might be counting localStorage items as cookies... maybe?

Will start working on this one. Quick testing on other sites seems to confirm it is counting localStorage items (so it is not always n+2). E.g. chromium-review.googlesource.com results in "5 in use", with 4 cookies and 1 local storage item. 

Looks like the problem comes from local_shared_objects_container.cc, while its method GetObjectCountForDomain returns the count of the cookies for the domain ( so, no third party), despite the similar name (that would seem to indicate the only difference is it includes third party) the method GetObjectCount returns the count of all objects (so storage, cookies, etc.) for all domains (third party included).
What I'm thinking of doing is:
-Rename GetObjectCountForDomain to GetCookieCountForDomain to make the difference in behavior more obvious.
-Create a GetCookieCount method that includes cookies for all domains (third party included).
-Use those in page_info to generate the count.

 

Nevermind, looks like GetObjectCountForDomain also counts all objects, not only cookies, so it would not be a rename, but also creating a separate GetCookieCount that only counts cookies. Now I'm a bit confused, because those two methods are (as far as I can see) only ever called from the page info to set that (cookie) counter.

This issue is still reproduced on Mac OS 10.13.3 from M60 to latest canary-72.0.3617.0.Could some one from dev please take a look.

Thanks..!!
