Does it also capture tracking crap? Wouldn't it be great to grab a URL via CL and read it local without anyone knowing?
If it does capture the tracking shite, would disconnecting from the internet be a good enough blocker?
By default, it will capture everything that would be interpreted/displayed. However, you can also run it with Selenium (and Firefox) instead of Puppeteer, and install your favorite extensions to block all the unwanted resources (there's a switch for that).
