Detect When A Browser Receives A File Download _TOP_
Liv Randzin
Background info:
I am working on an HTML5 Player and have a button to enter full screen.
When in full screen mode, I want the toolbar (for the player) to be hidden.
Then when user exits full screen mode I want the toolbar to be visible again.
I am able to detect when the fullscreen button I added is clicked, and when escape key is pressed.
However, I am not able to determine when the browser message "Exit Full Screen" is clicked.
Problem:
I need to know how to add an event or somehow detect when a user clicks
"Exit Full Screen (Esc)" when in full screen mode so I can get the player to
show my toolbar. Adding an event to the escape key did not fix my problem.
My question is: How do I detect the OS zoom. I do know how to get the browser level zoom based on the answer How to detect page zoom level in all modern browsers?, but as I change the OS zoom (on windows and MAC), the browser zoom returned is the same. So I want to compensate for the browser zoom, and that is the reason I am looking to find a way to determine the OS level zoom.
(Addition after edit):So I have changed my IP and browser information and the website can not reach this information anymore to prove that I am the same person using two accounts. Then let's come to the title: Can they see my MAC address? Because I think that it is the last way that they can identify me and my main question is that. I wrote the information above to mention that I changed IPs and I have some precautions to avoid browser fingerprinting (btw my VPN provider already has a service about blocking it). I wrote them because I read similar advices in some related questions but my question is that can they see my MAC address (or anything else that can make me detected) despite all these precautions.
Once they have a hunch that something is fishy they'll usually dig your posting history and find phrases or political views or mispellings or any pattern that's consistent. That is how sock puppet detection is done once you get past auto-detectors like referrer detection or IP address detection or username similarity detection (it's amazing how some people insist on using discoverable patterns when choosing usernames) etc.
The router, when it receives the frame will strip off the frame and reframe it for the next leg of the journey. I don't know much about ADSL framing but there will still be a frame used - some sort of dsl type frame. This time the to MAC address will be the MAC of the next node on the route to google.com. The from MAC will be the MAC of the broadband side of your router.
Ideally, traditional web browsers and their extensions should be built with your security and privacy in mind and shouldn't be detected by any external service. Since that is not the case, we better face the harsh reality together and ask: How much - or little - does it take to query what extensions are installed on a browser and get a list of them? Let's dive in.
Here's how the manifest JSON file looks like when you render it inside the browser. This example is taken from a popular Chrome extension, Google Translate. The request to render this page looks like this:
This next bit of detection is your user agent string - it is a technical bit of information that your web browser sends every time you load any website; we have decoded it to figure out what browser, operating system and device you are using.
