Is it possible to share data between different domains, not through query string?
As far as I know, cookies do not work. Because domains are not mine.
My idea is to create a data in my domain, and when I get to another, through a background script (tampermonkey for example), get the data I wrote in my domain and do the actions according to the routine that I made.
I do not know, maybe an internal database? Anyone have any ideas how to do this?
