Does the site function as expected when Shields are turned off?
Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration:
NO , I use all settings on aggressive and I decrease if I notice problems, however nothing works regardless of how permissive the settings are, only with the shield disabled it works again. (Google Translation)
Also, if you are getting this by being logged in Youtube with the adblocker, maybe you want to use Youtube without a google account?
I use Youtube and I have never seen the message, and what’s the point of watching a video and being logged in Youtube? not much, unless you want to comment on videos but you can do that without watching the video, or you want to keep history of all your watched videos which seems like you would just contribute to Google’s power on the internet with all the info you provide.
So watching videos without being logged in Youtube can be just the simplest solution.
