Third Party Local Storage Missing

[cosmux]

In /lib/tools.js you implement a function to retreive the localstorage for a page. In the comment you refer to // based on https://stackoverflow.com/a/54355801/1407622 .
Looking at this post there are two ways described to fetch the localstorage. While the implementation chosen does not collect localstorge for embedded YT-videos, the other solution does.
I coded a workaround reading the localstorage for all frames in a page as described in the post that and seems to do the cure, but my javascript skills are rotten - apologize.
