Mozilla Firefox is probably the safest and most versatile web browser that you can use for surfing the Internet. However, there will be times when being able to change your IP address in Firefox will make it even safer from a privacy standpoint.

Between entrepreneurs, travelers, and everyone else, there are numerous other reasons as well.

If you opt for the free option (public proxies), be aware of the risks and do not submit any online forms that require login information, personal or financial data. It is very difficult or impossible to know whether a free relay is being operated by a legitimate party.
