What should I check when the site behaves differently between browsers?

Compare the same conditions

Use the same public page address in updated browsers and note exactly what differs. Compare screen size, zoom level, sign-in state and any active filters before deciding that the browser itself is responsible. A saved search or dashboard view may depend on account state, so it is not a useful comparison with a signed-out public page.

Record whether the issue affects layout, navigation, loading or a specific control. Check for a visible error rather than repeatedly clicking a button, especially one that sends an enquiry or changes account information.

Troubleshoot without weakening security

After preserving unsent text, reloading may help identify a temporary problem. Review browser guidance for site data and permissions before clearing anything; removing site data can sign you out or discard local preferences.

Do not disable security protections, install unknown extensions or share credentials to make a page work. If the issue persists, send support the page address, browser versions, device and steps to reproduce it. Redact screenshots and say whether the problem prevents you from completing an essential task.
