![]() There’re many email platforms you can choose from. ![]() I will be raising a bug with Webkit in a bit.Read More Part 1: Maximum Video File Size for Gmail and More It correctly abstains from sharing third-party cookies, however, it shares them if the requested content is video. This is because Safari appears to have a bug in it. Ideally, Google should fix this issue by providing a different authentication mechanism that does not break when third-party cookies are disabled. Not an ideal solution because Google can now track you around the web. This will allow the embedded player to prove it is playing the video on your behalf. The fix: allow all websites to send your cookie # But because third-party cookies are disabled, the request for the attachment is not allowed to expose the session ID because the request is coming from a page. In the diagram, the video player outlined in red is hosted on server and the video player wants to play a video attachment hosted on. Gmail correctly rejects a request of this type because you don’t want strangers being able to watch your private videos. It’s makes sense for Google to re-use their YouTube player, however, the attachment is hosted in Gmail and if you read the Background section above you probably are starting to guess the issue: The embedded YouTube player page is not allowed to send your Gmail session ID when requesting the attachment and when it tries to load the video file it can’t prove it’s playing the video on your behalf. When you click to watch a video attachment in Gmail it overlays Gmail with an embedded YouTube player page.

Once you log out, you blow away your session ID and become anonymous (actually it’s much more complicated because more advanced tracking methods exist). This is why services like Facebook and Twitter want you to remain logged in. At other times, secretly watching and reporting the urls you visit to Google. Sometimes conveniently, for example when attempting to prove you have authorization to view a video attachment. Once you log into Gmail, this session ID can be used to identify you across the web. ![]() That’s convenient.īut there’s another way these cookies are used to track you around the internet. You don’t need to provide the email/password each time. Similarly, once you have a session ID the browser sends it each time you request to open a new email, so the server knows its you. From this point forward you can just provide the school with your ID# if you want to enroll in a class or check your grades. When you first enroll in a school you likely provide proof of identity like a birth certificate and in return you are given a student ID#. When you log in to a website like Gmail you provide your email/password and in the background Gmail’s servers send you back a cookie containing a session ID (for example: NRviSpoYm7mdkYB4W2471l). If you see “Third party cookies appear to be disabled”, then read on for the solution. To see if you’re video playback is broken for the same reason visit this page. Some browsers like Firefox have this disabled by default. Please try again later.” Let’s dig in.ĭisabling third-party cookies in my browsers was the cause of this issue. However, at some point the YouTube player started presenting me with the following message: “An error occurred. Gmail provides a really sleek mechanism for viewing the attached videos without leaving the browser by playing them in an embedded YouTube player.
