I'm working on a Chrome extension and I need to embed Google services (search, mail, contacts ...) in iframes. I've searched a lot and I get it is not possible because of Click jacking with the corresponding headers.
However, there's this extension, Black Menu (https://chrome.google.com/webstore/detail/black-menu-for-google/eignhdfgaldabilaaegmdfbajngjmoke?hl=en), that managed to embed most Google's services in iframes using custom URLs such as these:
With bm being obviously black menu.
So, I'm wondering, does this mean the developer managed to get exclusive/special access to Google search (and others) as mobile version to embed it?
Further more, I'm able to embed Gmail in an iframe, even if I got
X-Frame-Options:SAMEORIGIN
In the headers... Although this does not work every time.
Is it a cookie problem? Should I log in with Google across the entire browser? (And, if yes, how do I do that?).
