If you disable it globally intending only to use it on website by website basis it breaks. Still it does the job hiding those useless, space wasting, often wrong, so called "AI Overviews" from Google search.

Does this just hide the summary on Google or does it stop it from launching in the first place, as adding "-ai" to a search currently does?

Got it to get rid of the stupid ai overview on google and it works so far. Hopefully works on other things.

It works

This and uBlock to clean up the current state of AI garbage everywhere. If only it could remove the useless LLM bot they added to Firefox itself :\
