You can NOT use effective adblocker extensions with manifest v3, as it removed functions that they need (and impose some other limits to make them unable to update fast)

I think the prompts that ask to remove telemetry (or to be exact, stuff that try to modify system files) will just give you error. Similar to some current AI models that would just not run when it found some "prohibited" words in prompt.

1hr? Maybe just wear an action camera, if you can sit well in front of the screen during whole meeting. (j/k)

EDIT: For smartphone, get a selfie stand if you have place to set it up, do not try to hold the phone with your hand for 1 hour.

So it would block screen/video capture, but will it block sound-only capture, too?
