What it means in plain language
A web browser is a program used to download, interpret and display websites and applications running on the Internet.
Where it genuinely helps
A browser retrieves, interprets and secures web content, and different engines may handle the same code and privacy limits differently.
What to decide before acting
Design to standards and progressive enhancement rather than tying a critical journey to one vendor or extension.
How to tell whether it works
Test representative journeys in Chrome, Safari, Firefox and mobile with a clean profile, keyboard and slow network.
