Browser Compatibility: Why We Test Across Chrome, Safari and Firefox
Your visitors do not all use the same browser. Some are on Chrome, many on Safari via iPhones and Macs, others on Firefox or Edge. Each interprets web code slightly differently.
Cross-browser testing makes sure your site looks and works correctly for everyone, not just on the machine it was built on.
Why Differences Happen
Browsers are made by different companies and adopt new features at different speeds. A layout technique that works perfectly in one may need a tweak in another.
What We Test
- The latest versions of Chrome, Safari, Firefox and Edge.
- Both desktop and mobile versions of each.
- Older versions where your audience data shows real usage.
- Key journeys like navigation, forms and checkout.
Practical Limits
Supporting every browser ever made is rarely cost-effective. We use your real visitor data to focus effort where it matters and agree a sensible support list with you.
If you need a hand with any of this, your Progressive Robot delivery team is ready to help. Raise a ticket from the Support area of your client portal or speak to your account manager and we will guide you through the next steps.
