Firefox adds several new features to its updated browser, Tracking Protection, Tab Audio Indicators, and more. The main added feature is Tracking Protection, which will give users more choice and control over web browsing, and offer a private web experience.
Tracking Protection is added on top of Mozilla Firefox's Private Browsing mode, giving you control over the data that third parties receive from you online. The new version is available across Windows, Mac, Linux and Android. It will not save your browsing history or cookies, and will automatically block ads, analytics trackers and social share buttons that are trying to track your every move.
There's also an improved Control Center with site security and privacy controls as well as a revamped Login Manager sporting several improvements. The new Control Center is also in this update for keeping all the site security and privacy controls in a single place. Firefox 42 now has tab audio indicators on desktop, enable you find which sites are being noisy and mute them in one click, without leaving your current tab.
To prevent being tracked of the visit history and browsing habits, you may also use some other methods, such as use a VPN. Due to the ease of the crime, and the fact Wi-Fi Hotspots are typically frequented by folks with a little change in their pocket, a Wi-Fi Hotspot is a tantalizing place for bad guys to lurk. Protecting yourself when you're out and about, whether you handle sensitive data for your job and don't want to get fired, or you're just covering your browse history. VPN encrypts all your traffic, preventing DDoS and making sure nobody can steal your private data.
While, you may meet problem when the Internet connection is normal, the Mozilla Firefox can’t load any sites (but IE and Chrome can). That's strange, but I have met the problem when I use a VPN.
