Changing privacy settings
If you have your browser's privacy settings set to 'High' you may be unable to access Google Accounts. To resolve this problem, please add www.google.com to your browser's list of allowed sites.
If you're accessing Google Accounts from behind a firewall, proxy, or anti-virus program, temporarily disable the program and try signing in to Google Accounts. If disabling the program resolves the issue you're experiencing, then most likely the software is causing the problem.
We suggest consulting the program's online support center to find out why it might be interfering with your ability to access your Google Account.
Note: if you're using a work computer, the problem may be related to your computer's corporate security settings. We suggest checking with your system administrator.
