Vegetables do provide some nutrients and buffering, yet they're not an absolutely necessary main source IF you have access to good quality meat, eggs, fish, etc. Those things have a very high micronutritiants-content, as long as they are of good quality.
On Rabbit poisoning, looked it up. That is based on an absolutely purely protein-based diet with little to no intake of fat and carbs, as far as I understand that right now. I did not state that eating purely protein is okay, just that the body can make up for deficiencies in fat or carbs as needed. So eating nothing but chicken meat without any fat or carbs would likely cause rabbit poisoning symptoms as well. Which is, again, not what I stated.
Just get into the routine of going to ublock origin addon each morning, clear the caches and loading all filters. Close all youtube tabs and reopen them. Those daredevils are playing anti-anti-adblock with youtube via blocklists daily now.
Ah, if it doesn't work, disable all addons, restart browser, update filters, try. If it works, enable addons one-by-one until the method suddenly fails.
Also pi-hole and similar adblocking solutions can cause this now, so you might need to remove those, add exceptions or stuff. It's tedious, but doable.
Might be time to migrate to indiviuous as my new youtube frontpage (uses youtube as video source, nothing lost) or setup my own instance of it. My TV runs smarttubenext for years now, anyway, which is way better than the original yt app.
