Saver Drop-In doesn't work for Chrome Extensions
Even when you add your extension id to the Drop-Ins Domain list, triggering the Saver Drop-In from a Chrome extension currently results in an "Unable to communicate with the parent window" error because for all popups triggered from a Chrome Extension, the window.opener variable in the popup will be NULL.
Does anyone have an elegant solution for resolving this? So far the only potential fix I can see is generally a no-no with Chrome Extensions:
- Open a new page (perhaps in an IFrame) from a domain that is on your "Drop-ins domains" list.
- Include a Content Script in that page that injects (via "<script>" tags) the Dropbox saver code into the DOM of the page (as opposed to just running in the sandboxed extension DOM).

Unfortunately we don't have any official guidance or support for using the Drop-ins in a Chrome extension right now, but I'll be sure to pass this along as a request.
Thanks for the update Greg, I don't have a silver bullet solution but I would suggest that, if the developers were up to the challenge of making Drop-Ins work for Chrome Extensions, they take a look at Message Passing from Webpages: https://developer.chrome.com/extensions/messaging#external-webpage
