All browsers provide options to minimize the traces that can be left on the Internet and surf anonymously. Everyone without exception indeed offer the possibility to erase the history, browse privately, to prevent tracking websites, etc… They can also install new fresh proxies or security extensions to change its IP address, block ads, cookies, etc… But can we have confidence in browsers that belong to companies actively involved in the collection of personal data? Chrome (Google), Internet Explorer (Microsoft), Safari (Apple) or to a lesser extent Opera (Opera Software) all have in common to be managed by companies motivated by profitability.
At a time when personal data have owned price of gold, we have chosen to focus on a browser “open source”, namely Firefox. Unlike its competitors mentioned above, it has a priori no commercial interest in exploiting the personal data of its users. To provide certain services such as Firefox Sync, Mozilla, however, states have to gather more information about its users as we detail a few months ago here. Of course, this is not the only open source browser, but its rich ecosystem has no equivalent. It has indeed a wide range of tools and extensions to secure your connections.
Browse in private mode
Whether Chrome, Internet Explorer, Safari, Opera or Firefox, you can start a private browsing mode. In Firefox, just click on “Tools” then “Start Private Browsing”. But beware, contrary to what one might think, this function does not aim to make you anonymous, but to prevent the browser to save the pages visited and passwords, and disable the auto (re-recorded information when you fill out a form).
This function is useful when you share a computer with other people and you do not want them to know your online business, but it stops there. As stated in the FAQ Firefox, your employer or your ISP can still see the pages you visit and your IP address.
The browser of the Mozilla Foundation offers a variety of tools to reduce the traces you leave on the Internet. As with all browsers, you can erase cookies, cache, browsing history, downloads and forms. In short, you can make a clean sweep of your online business. In return, you get more of certain features handy, saving passwords, auto complete forms of online pop-up dynamics of previous queries made, etc… To optimize the cache cleaning the computer and browser, it is recommended to also use a tool such as Clean UP.
