Parsing data from PDF files opened in Chrome tab

Hi everyone. Maybe someone has experience in parsing data from PDF files that open directly in the Chrome tab, the situation is as follows :
There is a link to a PDF file on a website. It opens directly in the browser. And from it you need to get the text.
I tried to put an extension that opens the file in HTML5 (Uses HTML5 to display PDF files directly in the browser), but this is where I stalled ... webscraper can't do it, because in the address bar first comes "chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/"....
WebScraper gives an error
FAILED_TO_CONNECT_TO_CHROME_TAB {"message": "Could not establish connection. Receiving end does not exist."}

Maybe someone has a positive experience in solving this problem?
