Cookie question
Can a 3d party connected to one browser read the cookies in another
browser's cookie jar? (like IE and FF or FF and the AOL browser that looks a lot like FF.) |

If you haven't purposefully modified two browsers to "share" a common profile folder, the answer is "No", they shouldn't be able to snoop. The software designers were supposed to go to some degree of effort, to prevent that from happening. Sometimes this is taken to extremes, when an AV product keeps a browser in a "sandbox". ******* Say I go to "able.com" and read a delightful web article. I look at the bottom of the browser screen, and I see "googleadservices" flash by. Later, I go to the "baker.com" site and see an advert for able.com or see pictures of some product I was interested in on able.com . I look at the bottom of the screen and I see "googleadservices" flash by. Hmmm. Each time you visit a web page, a metric ton of domains flash by. Perhaps the domains record their own cookies ? Perhaps you would select the option that tosses cookies when you drop a page ? There is "incognito mode" on some browsers, but I don't know how well any of these techniques work when the browser pages "leak" from one page to the next. If particular companies always get to place .js code on the web pages you visit, I doubt your privacy will be maintained. And a "Googlean" thing is present on just about every page you visit. Sometimes, for fun, I shop for "socks" on Amazon.com . Then later, if I visit the CNN news site, I will get to enjoy pictures of "socks" on the right hand margin of the screen. It's fun to jerk their collective corporate chains :-) If I were to switch browsers, my "interest in socks" should not travel with me. As all the involved cookies were contained in the profile of the first browser. The second browser I pick up and use, none of the cookies in there have recorded my interest in Argyle Socks quite yet. And web companies do not typically use IP addresses for tracking you, as that's considered an unreliable method in a "DHCP universe". If it wasn't for that, I could see them being tempted to do "associations" via IP address. Then two browsers could see sock adverts, just because they both came from 1.2.3.4 IP address. (Click this, to see lots of sock adverts where they don't belong, later :-) And so on.) https://www.amazon.com/Mens-Navy-Ora.../dp/B01N52HH3Z My search history and product view info at Google says "I have a bizarre taste in socks". And that's what I want it to say. Paul I have alarming experiences with facebook that make me think they are sniffing coolies on my machine. My dog has a page. I am not on it and I have carefully avoided being there at all but I get pop up ads for things my wife and I just bought on Amazon. They had to be sniffing a cookie or something. I really should get my dog his own computer I guess ;-) |

Cookie question
My dog has a page. I am not on it and I have carefully
avoided being there at all but I get pop up ads for things my wife and I just bought on Amazon. That probably has got nothing to do about cookies, and everything about how that company (and others) link "people" together - on *their* servers, something which you cannot do squat about. In the worst of circumstances your computer has a static IP. In another amazon could have used machine fingerprinting, by which they could have noticed that you and your dog use the very same computer. In yet another their page uses flash player, and stores the data there (might well be a cross-browser storage. who knows ...) Regards, Rudy Wieser |

I look at the bottom of the screen and I see "googleadservices" flash by.

It's fun to jerk their collective corporate chains :-) When (ITIW: I think it was) Bill Clinton was president, "socks" was First Cat (in the same way Hillary was First Lady). I don't have any pictures of socks, but I do have an audio file that purports to be him (?). (It's a .au file! From 1995.) He (?) doesn't sound at all pleased; I suspect was prodded, or similar, to make a noise for the recording. If I were to switch browsers, my "interest in socks" should not travel with me.

I wonder how many of your readers have too - and whether Amazon have noticed a puzzling spike in interest for them as a result!

Sniffing cookies does sound appropriate for a dog. Especially if you put, shall we say, unusual ingredients in your cookies. (Sniffing coolies I'll leave to others to comment on!) I really should get my dog his own computer I guess ;-) In another newsgroup I take, that would trigger a list of suggested makes - though I can't think of any that are particularly canine. -- J. P.

IE uses text files with extension .txt (changed later to .cookie and later into a database) in which to save cookies (*). Firefox uses its own sqlite database. https://answers.microsoft.com/en-us/...f-dd438fdc20cd There are tools that can dig into sqlite databases because SQLite is not created by Mozilla. It is used by many authors, so there are standard directives that can be issued against the database to create, delete, change, and query the records in an SQLite database. However, although the structure within is standardized by SQLite, the contents of the fields within each record can be any proprietary format. The change to IE's cookies is new. Even back when they were .txt files for IE, web browsers didn't bother sharing cookie data. Now that Mozilla has their database and Microsoft has their database, they would have to employ forensics to dig into those databases hoping to ferret out some information. Not worth the effort. Each web browser has its own DOM Storage, too. They don't share on that data, either. Cookies had a limitation on size so they couldn't hold a lot of data. DOM storage is huge by comparision. I think the difference is like 4K to 4MB. https://en.wikipedia.org/wiki/Web_storage |

Regards, Rudy Wieser That is not likely since the ad was so specifically targeted at me. It pretty much had to be something they sniffed off of my PC and it is not a static IP. I am not really sure how Facebook would find me otherwise since my dog is the only one in the house on FB and I really avoid any reference to myself. I even keep my "face" off of Facebook. (I guessed they were using facial recognition long before they admitted it) His "friends" are a pretty diverse group, most not directly tied to me either. He takes friend requests from a lot of people we don't know, just to increase the clutter in the "network" and make the valid connections get lost in the grass. When I downloaded the data they admit to, there was not much there. My Flash is an old version so it will not run unless I let it (from the nag screen) and I don't let it run often. |

If they can see the meta data without actually clicking the "allow" button using an older version, that would do it because I am sure Amazon uses Flash. |
