Block Ads and Trackers in Firefox browser on the Computer

The Firefox browser offers privacy settings that help us block online trackers using the Enhance Privacy Protection modes. We can switch to the strict mode or choose the custom mode to configure the tracker protection to avoid spam advertisements.

Alternatively, you can install the Ad Blocker add-on on the Firefox browser to completely stop ads.

Bottom Line

Firefox has the built-in support to block online trackers, which can help us safeguard our online browsing privacy. It can limit the data sent to advertisers that can protect from displaying the personalized ads.

However, we can always install the ad blocker add-ons to the browser to stop all kinds of advertisements. It is also recommended to enable the pop-up blocker to avoid falling into misleading ads.
