I experienced, that some Websites and WebApps didn't show any content anymore as soon as I had installed the chrome extension of this App. I was willing to rate 1 Star here, because my first email wasn't answered to (maybe it went in spam folder of the support). On a second attempt I got a quick answer with a trouble shooting page which maybe also could help others with the same problem, so I paste it here: https://www.blurweb.app/help/few-website-do-not-load-when-blurweb-app-installed
