Six months ago, Firefox users were outraged by the new Mozilla management’s attempt to install AI by default, which couldn’t be disabled in the settings. This could only be done through a special procedure. Mozilla eventually created a dedicated tab in the settings where AI could be disabled. But today, I discovered that this tab has disappeared again in the new version. I offer Firefox users a procedure to disable AI.
Disable the integrated AI chatbot in Firefox
8.1. Firefox features an integrated AI chatbot. By default, it’s turned on. This might negatively affect both your privacy and the performance (speed) of Firefox.
Thankfully, it’s rather easy to disable this feature. Like this:
a. Type in the URL bar of Firefox:
about:config
Press Enter.
b. Now you’re being presented with a warning. Ignore it and click on the blue button “Accept the Risk and Continue”.
c. Copy/paste the following search term into the configuration search box:
d. Find the following entry: browser.ml.chat.enabled
That’s currently set to the boolean value true. Double-click on it, so that it changes into false.
Do the same for the entry: browser.ml.enable
e. Close Firefox and re-launch it.

Got version 152.0.3 today on Linux (Arch) and the tab is still there, just moved down a few in the settings list. Is still set to disable everything with “AI”. For me it is just below “Languages” in the Settings menu.
Seems they "refreshed’ the Settings page, they even have a little info bubble at the top:
“Same settings, new look!
We reorganized this page so it’s easier to scan and explore. Your personal settings haven’t changed, and everything’s still here. Tip: use search to jump straight to what you need.”
