One of the most traditional Internet browser making companies, Mozilla has announced a pre-beta version of its Firefox browser for Mac, Windows, Android, and Linux. It is featured with an updated ‘private browsing mode’ that enables the browser to block the web elements that could track the users’ behavior, such as analytic tools and social network services.
“Our hypothesis is that when you open a Private Browsing window in Firefox, you’re sending a signal that you want more control over your privacy than current private browsing experiences actually provide,” Mozilla said in a blog post. “The experimental Private Browsing enhancements ready for testing today actively block website elements that could be used to record user behaviour across sites.”
The pre-beta version of the Firefox also allows the users to manually enable/disable the tracking in the private mode for the current browsing session, as it could hinder the rendering of some web pages.
“Since Private Browsing mode doesn’t keep any information about your browsing session, when you disable Tracking Protection for a site, it only lasts for the session. When you start a new Private Browsing session, Tracking Protection will be turned on for all sites,” Mozilla said on a support page.
Previously, Mozilla has been urged to update their Firefox to 39.0.3 and higher. As few security analysts has discovered that some malicious advertisements were exploiting a vulnerability in Firefox’s PDF Viewer. These advertisements search for sensitive files on users’ local file systems.
In addition, developers are making the add-ons more secure. The Mozilla has further announced that its new Firefox update also verifies whether an add-on meets its guidelines and criteria. If it doesn’t, the browser won’t allow the system to download and install it from the official store, however, if the user trusts the plugin then it could be installed with additional methods.
To avail the newly announced release, users will have to download and install the Firefox v42 to their systems. It will be available to download from Aurora (similar to Nightly builds, but a tad more stable). Moreover, to enable tracking protection, the users have to visit the about:config, and find the options privacy.trackingprotection.enabled and privacy.trackingprotection.pbmode.enabled, and flag the latter option as True. Meanwhile, to enable it in regular browsing sessions, flag the former feature as True.
It is, however, explicitly stated that the employer, system administrator or the Internet service provider are still able to track down the information.
