Use a current mainstream browser on a supported desktop, laptop, phone or tablet; an up-to-date browser gives the best chance of correct uploads, payments, chat and profile editing.

What you need to know

• Keep Chrome, Edge, Firefox or Safari updated to a current release.
• Allow normal JavaScript, cookies and secure site storage required for sign-in and interactive features.
• Browser extensions, privacy tools, VPNs and content blockers can sometimes interfere with uploads, popups, checkout or embedded tools; test a private window if something behaves unexpectedly.
• Use a stable connection for large uploads or payment actions.
• If a problem is device-specific, tell support which device, operating system and browser version you tested.
