I am using Firefox on iPhone (together with DuckDuckGo as my preferred search engine) and I want to configure it in the most secure and reliable way, without running into blocked pages or limited results.

Here’s what I would like step-by-step help with: 1. HTTPS-Only Mode – how to enable this permanently so all sites load securely. 2. Tracking Protection – which level is best for privacy without breaking websites (Standard vs Strict). 3. DuckDuckGo Setup – how to make it my default search engine in Firefox iOS. 4. SafeSearch – how to set it to the best option (Strict, Moderate, or Off) depending on my preference. 5. General Security – any other recommended settings (cookies, history, etc.) to improve private browsing.

My goals are: • Reliable browsing without “HTTP not allowed” errors. • Strong privacy protection. • Smooth experience without unnecessary restrictions.

Could you please guide me step by step on how to set this up correctly?

Thank you in advance for your support!

Hi Don,

I like how thoughtful and prepared you are! Let me try to help with what I know:

1. HTTPS-Only Mode – how to enable this permanently so all sites load securely.
To my knowledge, FIrefox will upgrade your connection to HTTPS protocol by default (See Firefox connection upgrades - HTTP to HTTPS).
2. Tracking Protection – which level is best for privacy without breaking websites (Standard vs Strict).
That'll be Standard for sure. More about that Enhanced Tracking Protection in Firefox for iOS
3. DuckDuckGo Setup – how to make it my default search engine in Firefox iOS.
For that, please check out Change your default search engine in Firefox for iOS.
4. SafeSearch – how to set it to the best option (Strict, Moderate, or Off) depending on my preference.
Safe search is configured on the search engine level, not browser. If you're using DDG, you may want to refer to their official documentation.
5. General Security – any other recommended settings (cookies, history, etc.) to improve private browsing.
There are a few things you can do to enhance your privacy while using Firefox for iOS:

I hope these helps, and happy browsing with Firefox!
