I don't have a complete guide for the AI stuff, but if you disable all the telemetry available in the settings, it should already disable some of the experimental stuff (the Mozilla Labs thing or whatever it's called). You can tell that it's off because the category will be missing in the settings and about:addons will only show your own addons.
As for about:config, I do have some settings, but my notes are a mess:
>browser.tabs.groups.smart.userEnabled
set to false
>browser.tabs.groups.enabled
if you want to disable groups entirely
As for the chatbots in the sidebar, I have the following notes written down:
Disable chatbots in Firefox: Settings > General > Show sidebar > Right click > Customize sidebar > uncheck Ai Chatbots
>Or: about:config:
browser.ml.chat.enabled false (default is true)
>Bonus:
"browser.ml.chat.sidebar", false
Sorry if I forgot anything, my notes are a mess.
