I'm already seeing sites telling how to block FF's AI baby steps ... which I discovered were already present in the FF I use. https://equk.co.uk/2025/10/28/firefox-forcing-llm-features/
Who knows how badly they'll mess themselves up by not being -completely tranparent- about this stuff and -not- making it really easy to disable. It's still possible to download older versions of FF to fall back on ... in case they lose their minds.
