I have a YouTube video embedded in my mobile webpage. On desktop, it plays properly. However, on mobile phone (emulated on Android), it stops after some time throwing an error. When I debugged in console, following errors are generated: Failed to load resource: net::ERR_FAILED XMLHttpRequest cannot load http://r13---sn-nx57yn7s.googlevideo.com/videoplayback?source=youtube&ipbit…s_redirect=yes&mm=30&ms=nxu&mt=1410325650&mv=u&range=0-65535&keepalive=yes . No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://www.youtube.com ' is therefore not allowed

While debugging AngularJS in Chrome inspector I often face the situation when I know that some variables are defined, and I can inspected them by hovering a mouse over them in Chrome inspector. They also appear in 'locals' tab. However, when I try to add them to watch tab or evaluate them in console by typing the variable name I get "undefined". See picture(notice variable 'xhr'). Can anyone explain the reason why sometimes variables are shown as undefined in watch tab and console, when they aren't actually undefined in current scope? And, if it's possible, how to make watch window and console

Is it possible to use chrome devtools to execute the terminal command node myfile.js , so the chrome console would output all console.log s from my code? I have got some terminal plugin installed in my IDE and I use some keyboard shortcuts when I want to run this command on my files, to get my logs immediately (like when running html+js in the browser) but it prints out just plain text. Chrome can recognize the output data type and structurize it well (arrays, objects) , what is really cool. I've already tried out node inspect-brk but its purpose seems to be quite different than just printing

I am have issues using the remote debugging feature of the Chrome Developers tools with my Android device (LG Nitro running Android version 4.0.4). It was working perfectly several days ago but now my device never appears on the about:inspect page. I have followed and carefully considered these instructions including the troubleshooting tips. I have also searched for the answer to my problem but have not been able to find anything that works. I am using Chrome version 35.0.1916.141 on my Android device and version 35.0.1916.114 on my PC (Windows 7). Neither says any updates are available.

I am new to both JavaScript and Chrome development, and am trying to create an extension that injects content/CSS in certain web pages. Simple enough, but the catch is that to do so it requires looking through a significant amount of data in local storage. From what I've read so far, the correct way to do this would be either: Reading the required data ( JSON serialized ) from storage directly from the content script every time the page is visited, or Maintaining the state in the extension background page and transferring the required data ( also JSON serialized ) to the content script
