Launched earlier this month, Firefox 13 introduced many new and advanced features such SPDY protocol support, a new home-screen with tabs etc.
But with it, it has even sparked a new debate about the user’s privacy that can be at risk. The problem does not involve any case of external breach in the security of the browser but rather due to the lax presentation of the personal data, concerns about privacy has evolved.
The new tab feature has become the focal point, as it shows different sites that the user visits during his session. But the problem is that in-order to show the thumbnails on these tabs, snaps are taken at regular interval. So now if the user is filling his/her bank information or any such important data then chances are that it would simply display on these tabs and thus private information can be revealed.
Mozilla Corporation has duly acknowledged the issue , so soon this problem will be fixed but by that time, it is recommended that users should be alert especially while using shared computers, for that purpose, one can even enter the Private Browsing Mode.
The risk of stealing information through tabs is small but it should not be neglected.
