Mozilla keeps your browsing private with new Tracking Protection feature

New feature blocks ads, analytics and other Web features that keep tabs on users

Firefox users who want to better hide their browsing habits have a new tool to use, thanks to Mozilla’s launch of Private Browsing with Tracking Protection in its latest browser release on Tuesday.

The new feature is an enhancement to Firefox’s Private Browsing mode, which deleted users’ browsing history and cookies after they closed a private window. Tracking Protection adds an extra layer of privacy to that by blocking code embedded in websites that tracks the way people behave around the Web. That means it will block a lot of ads, along with analytics tools and some social sharing buttons in order to help users keep their browsing habits more closely under wraps.

It solves one of the key problems with the private browsing modes that browsers like Firefox, Chrome and others have pushed in the past: while they may keep a user's browsing history under wraps for people looking at that person's computer, tracking features of websites will still be able to keep tabs on them.

The change isn’t good news for companies that rely on tracker-based advertising to make money, however. Although Firefox users are only a small (and shrinking) part of total browser users — and Private Browsing users a smaller percentage of that still — the new feature means that they won’t get money from ads that aren’t displayed to people using Tracking Protection.

That said, advertisements that don’t track users will still show up when users have Tracking Protection enabled, so that’s one way for publishers to continue monetizing their work.

It’s all part of a push Mozilla is making (through Firefox) to provide tools for users who want to curb tracking of their browsing habits, but the company says that it’s not out to kill advertising or ad-based businesses on the Web. Denelle Dixon-Thayer, the company’s Chief Legal and Business Officer, said in a recent blog post that the organization wants to push an open ecosystem that gives publishers and developers a way to monetize their work while balancing user privacy.

All of that is not to say that people who use tracking protection will be able to keep their browsing completely private. Internet service providers and network administrators will still be able to see what they do, for example.

Mozilla is also in a unique position to roll the new feature out. Both Microsoft and Google have advertising-based businesses that rely on tracking users in order to make money, so it’s not in their best interests to build similar features.

Were Apple to launch a similar feature in its Safari browser, it would likely provoke a swift, negative reaction from publishers that the company is trying to court to build apps for its platform and share content through iOS 9’s News app.

Features like this may drive renewed interest in Firefox at a time when the browser is losing market share to Google Chrome. Creating these sort of user-centric features will be key to differentiating Mozilla’s offering in a crowded and tough market, especially when the company’s competitors may not be as interested in building similar functionality.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
