Firefox Privacy Protection makes website trackers visible – Naked Security


Mozilla has added another privacy tweak to Firefox version 70 – the ability to quickly see how often websites are tracking users.

The company calls it the Firefox Privacy Protection and users can access it by clicking on the address bar shield icon.

The drop-down itemises different kinds of trackers detected on each site, such as general-purpose third-party trackers (Google Analytics on a news site, say) or cross-site trackers which follow users from site to site.

In our testing, the feature worked well, although users might not notice many trackers being caught if they’ve already set Firefox’s Enhanced Tracking Protection (ETP) to a strict setting.

What it does visibly confirm is how many trackers Firefox now blocks of various types. Users can get an overview of all blocked trackers by clicking ‘show report’ at the bottom of the Enhanced Privacy Protection drop-down box.

Don’t look now

To back up its claim that privacy protection is worth having, the company released figures showing that Firefox had blocked 450 billion cross-site tracking requests since 2 July, shortly after ETP was first introduced.

Since then, that’s risen to 10 billion blocks per day:

Much of this work has been behind the scenes – practically invisible to you – making it so that whenever you use Firefox, the privacy protections are working for you in the background.
