Blocking URL list in Google

The management of Google Chromebooks uses a set of URL's that block traffic to four sets of resources.


  • Internal Chrome Dialogs
  • External Search Engines
  • Local Development extensions
  • Google Sign-in sites.


The content is always updating as new resources emerge but the list below is commonly used for education.

myaccount.google.com/security#signin
accounts.google.com/ManageAccount
photos.google.com/login
plus.google.com/u/0/?referer=gplus
aboutme.google.com/u/0/?referer=gplus


The restriction to external search engines is not to protect Google's business model but to ensure that 'safe search' is not easily bypassed.


 A second approach blocks all chrome://* targets and then operates a whitelist.

chrome://*
chrome.google.com
https://myactivity.google.com
https://accounts.google.com/AddSession
https://accounts.google.com/ServiceLogin?elo=1
accounts.google.com/Logout
accounts.youtube.com/accounts/Logout2

Whitelist:
