Hi Don, I like how thoughtful and prepared you are! Let me try to help with what I know: <blockquote>1. HTTPS-Only Mode – how to enable this permanently so all sites load securely. </blockquote>To my knowledge, FIrefox will upgrade your connection to HTTPS protocol by default (See [[Firefox connection upgrades - HTTP to HTTPS]]). <blockquote>2. Tracking Protection – which level is best for privacy without breaking websites (Standard vs Strict).</blockquote> That'll be Standard for sure. More about that [[Enhanced Tracking Protection in Firefox for iOS]] <blockquote>3. DuckDuckGo Setup – how to make it my default search engine in Firefox iOS. </blockquote> For that, please check out [[Change your default search engine in Firefox for iOS]]. <blockquote>4. SafeSearch – how to set it to the best option (Strict, Moderate, or Off) depending on my preference.</blockquote>Safe search is configured on the search engine level, not browser. If you're using DDG, you may want to refer to [https://duckduckgo.com/duckduckgo-help-pages/features/safe-search their official documentation]. <blockquote>5. General Security – any other recommended settings (cookies, history, etc.) to improve private browsing.</blockquote>There are a few things you can do to enhance your privacy while using Firefox for iOS: * [[Mobile - Manage Firefox data collection and privacy settings|Set up Firefox data collection and privacy settings]] * [[About private browsing in Firefox for iOS|Learn more about Private Browsing]] (psst, it doesn't make you anonymous on the internet) * [[Set up a passcode and Face ID in Firefox for iOS|Set up passcode and FaceID to secure your saved passwords]]. * If you want to use Private Browsing by default, I'd recommend using [https://apps.apple.com/nl/app/firefox-focus-privacy-browser/id1055677337 Firefox Focus] if you haven't already. I hope these helps, and happy browsing with Firefox!
