Firefox New Tab Thumbnail Could Expose Your Data

Not many browsers enjoy the huge popularity of Firefox. But the browser might lose some image points, as its new tab thumbnail is said to expose your personal data.

Recently, Firefox has released a new version of its browser. Firefox 13 has brought along a series of new features, which from the layman’s point of view look pretty harmless. However, several users, have panicked over the possibility of Firefox’s new tab thumbnail of leaking private data.

The Register was the first media source to take on readers and users’ complaints about Firefox 13’s new tab thumbnail. One of the newspaper’s readers, Chris announced the new feature is “taking snapshots of the user’s HTTPS session content”. This means that online banking and webmail sessions can easily be exposed.

Chris said it opened the new tab feature and was “greeted by my earlier online banking and webmail sessions complete with account numbers, balances, subject lines etc”. In a nutshell, Firefox’s new version is giving ease of access to the content all online users are most afraid of losing.

Mozilla took notice of the problem and said the new feature’s problem is indeed in need of a fix. “We are aware of the concern and have a fix that will be released in a future version of Firefox. “Mozilla remains resolute in its commitment to privacy and user control”, reads the company’s statement.

The company also added: “The new tab thumbnail feature within Firefox does not transmit nor store personal information outside the user’s direct control”. So, until Firefox releases the new version and the fix, all you have to do is delete your browsing history and thus keep your data safe.

Another way to prevent Firefox’s new tab thumbnail feature exposing your data is to “switch back to using blank new tab screens by clicking the square icon in the top right corner of the browser”. That is going to “change the default preferences to show a blank page, rather than the most visited websites when a new tab is opened”.

Mozilla also advised users sharing computers or using the browser from a public computer to “follow best practices for protecting their privacy by utilizing the built-in privacy tools in Firefox, such as Private Browsing Mode”.
