Is there a way to get data from other pages? I mean when you open specific page, the script runs a search on the web to look for data and then you insert that data into the loaded page you loaded before?
Example would be say you looking to buy a chair, you looking at one seller web page but the extension looks up prices from other sellers and shows a graph or values, then you click on the value to go to that other seller page.
From what i understand you can manipulate DOM of opened tabs, but is there a way to load DOM from another page that is not in the opened tab?
