Android 17’s latest update looks tiny — what actually changed, and what free privacy tool did Firefox just ship?

Small platform updates often matter through cumulative polish—permission behavior, background activity, battery use, and compatibility—rather than one dramatic feature. The accompanying Firefox privacy tool is useful only if it fits your real threat model, so check what it blocks, whether it works outside Firefox, and what data it collects itself. Install system updates from Settings and privacy tools from the official app store, then review permissions instead of assuming “privacy” means no data leaves the device.
