You could however, use a tool like External Application Button [0] in order to send the URL of the page to a script/program, which in turn can make the body of the page parsable by downloading the URL it gets, automating some action on it. I use it pretty often to automate downloads with yt-dlp or opening a picture directly in GIMP from the browser, but since you're invoking a bash/python/whatever script, the possibilities are basically endless.
