The traditional browser wars are over. Now the main activity is how the browser interact with Mobile devices and search engines. With Goggle and Amazon expanding the business models of how they provide results to their users and use captive browsers the next set of browser wars will be in the courts of the U.S. and EU.

There currently are and soon will be more mandated requirements for what can be done with users' information. Most notable are the EU's GDPR and the California Consumer Privacy Act of 2018. Every type of organization that has information and data on third parties must be aware of how that data is accessed, stored, distributed, shared, sold, and archived.

When people talked about browsers back in the 1990's they had no idea about the level of complexity they mandated requirements would add to the process.
