Let's say first page is microsoft.com and the second one is google.com
I can make first page send POST data by using console but I cannot reach that data it in google.com in any way I can think of. After I reach it, I will also need to use it.
Is it possible to do that with only JS?
I think I can do that with something like iMacros and chrome extension development but I want to do it in JS.
Any ideas?
