In celebration of its 10th year anniversary, Mozilla’s Firefox gets a number of news features that will give users more control over their information online.

The most remarkable change is the new Firefox Forget button, which allows users to quickly clear their browsing history, cookies and other recent activities. Firefox VP Jonathan Nightingale explains they’ve added this feature to boost the privacy of users – some of whom share a computer with their friends or family.

“Forget gives you an easy way to tell Firefox to clear out some of your recent activity. Instead of asking a lot of complex technical questions, Forget asks you only one: how much do you want to forget? Once you tell Firefox you want to forget the last 5 minutes, or 2 hours, or 24 hours, it takes care of the rest.”

DuckDuckGo Search Support

In addition to the Forget button, Mozilla also added DuckDuckGo as a pre-installed search option in Firefox for Windows, Mac, Linux and Android. The move is a response to users’ concerns about how to better control their digital info, as a Harris Poll global survey revealed majority (74%) of internet users felt that internet companies knew too much about them.

“Search is an integral, and deeply personal, part of online life,” said Nightingale. “The things you search for can say a lot about who you are.”

With that in mind, Mozilla added support for privacy search engine DuckDuckGo in Firefox, so users will feel more secure about their online searches.

“Other engines may use tracking to enhance your search results, but we believe that’s a choice you should get to make for yourself,” Nightingale added.

An option to walk through Firefox’s new privacy options, including Forget and DuckDuckGo, is available when users update their Mozilla browser to the latest version. The Privacy Coach also provides info about settings and add-ons to control Firefox on Android devices.

The rest of the updates Mozilla announced on its anniversay are targeted at more technical users, including a privacy-focused program called Polaris and a new Firefox Developer edition customised for Web developers.
