Browser compatibility testing is the process of making sure your website works consistently across different browsers and devices. I've been through this many times, and it's essentially about checking that your layout doesn't break, forms submit correctly, and images load properly whether someone visits from Chrome, Safari, or Firefox. It's tedious but crucial work that saves you from those embarrassing 'this site looks broken on my browser' complaints.
