When you click the Edgar icon to access the Edgar Chrome extension, do you see a blank white box like this?
This means you need to enable cookies! To do this, click the button that looks like three lines in the upper right corner of the Chrome window and choose Settings:
Click Content settings.
Click Allow local data to be set (recommended). If you really want to keep cookies off, click Manage Exceptions and set up an exception for *meetedgar.com and set it to Allow.
Restart Chrome, click on Edgar's icon to launch the extension and you should be all set!
