Optimize Firefox (PC / MacOS) for data protection

Firefox Download

Firefox is an alternative to Chrome or Safari. In this post, I’ll show you how to get the best data protection out of Firefox.

Google’s Internet browser Chrome is not recommended for privacy-oriented browsing. Integrated browsers such as Safari or Microsoft’s Internet Explorer, now Edge, are also not recommended, as updates are sometimes a long time coming.

Please note: The language on the screenshots is in German. This does not change the position of the elements.

01. General settings

After downloading and installing Firefox from the website, you must first change the default browser in the system. But you can do this directly in the Firefox settings.

To do this, open the Firefox settings with “CMD +,” on MacOS, or on the Windows PC by entering “about: preferences” in the URL address of Firefox and pressing Enter:

Firefox Default Browser

On the same page at the bottom we have to open the connection settings and the option “DNS over HTTPS”:

Firefox Connection Settings

Cloudflare can remain selected there. When that is done, you can click on “Ok” and the settings are saved.

02. Configure search

After we have set the general settings, we go to the menu to be found on the left on the tab “Search”. There we change the standard search engine to “DuckDuckGo”, deactivate search engines that are not required and delete them from the list and deactivate all boxes under the item “Search suggestions”:

03. Data protection & security

Under the menu item “Search” on the left side we find the menu item “Data protection & security”. There we navigate next and select the Custom tab under “Improved protection against activity tracking” and set the following:

Firefox Privacy & Security

When asked whether we want to send “Do Not Track” requests to websites, we tick the “Always” box and set “Cookies & website data” so that our data is deleted when Firefox is closed.

The next point is “access data and passwords”, there we remove all ticks from all boxes, because we don’t want Firefox to fill in our data automatically.

We configure the history and address bar as shown in the following picture:

Firefox Chronik & Addressbar

After these settings you will find settings for data collection by Firefox, the hooks for which we remove all and security points for fraudulent content. There, in turn, we check all boxes.

I advise against the possibility of synchronizing your Firefox browser and data, because then all bookmarks, possible chronicles and saved form / password data will be uploaded into the cloud, where they could be exposed to security risks.

With these settings, you are pretty well positioned when it comes to data protection and you don’t have to worry much while surfing. Nevertheless, I would like to recommend 2 extensions that provide additional protection when surfing:
