In the context of a user script, for example executed by Tampermonkey, is it possible to communicate between two pages of different domains, which set 'X-Frame-Options' to 'SAMEORIGIN'?
I know about this way of sending messages from one page to another by using iFrames and postMessage, but when working with sites you dont control, like in my case Stack Overflow and Google (working on a bot to automate something for me), you'll get the SAMEORIGIN error when trying to create the iFrame.
But I thought since I'm able to insert script in both pages, it might be possible to pull off some workaround or alteate solution.
