fixup! Firefox preference overrides.

// tor-browser#42054: make sure search result telemetry is disabled.

pref("browser.search.serpEventTelemetryCategorization.enabled", false);

// tor-browser#42872, #42555: Disable translations.

// Translation have a bad UX in 128 (and with our config). Maybe we will

// re-enable after auditing and fixing the UX (tor-browser#41837).

pref("browser.translations.enable", false);

// ML components that we want to hide from the user. See tor-browser#44045.

// Many of these preferences are locked because the component is entirely

// removed, so they could not be functionally enabled.

// tor-browser#42872, #42555, #44045: Disable ML translations.

// Maybe re-enable after auditing and fixing the UX (tor-browser#41837).

// NOTE: whilst the "translations" component is still included in the build, we

// lock the preference because the engine is excluded and the

// "translations-models" RemoteSettings needed for the engine is empty.

pref("browser.translations.enable", false, locked);

// Disables many (but not all) ML engines. Note, this does not have overall

// control over exposure to ML features. tor-browser#44045.

// Disable third party AI chatbot. tor-browser#43989.

// pdfjs.enableAltText controls whether MLManager is created,

// pdfjs.enableGuessAltText controls whether the MLManager can create an ML

// engine. pdfs.enableAltText controls whether the latter preference can be

// changed by the user in the UI, but also has the side effect of hiding the

// UI controls for the non-ML preference pdfjs.enableNewAltTextWhenAddingImage.

// See bugzilla bug 1943456 comment 12.
