Browser compatibility — CertForged Help

What we test on

Chrome, Firefox, Edge, and Safari — current and previous major versions.

Desktop and laptop — any OS.

Mobile

The site renders on mobile but the simulated terminal really wants a real keyboard. iOS Safari and Android Chrome work for browsing content; for active practice, use a laptop.

Things that break in older browsers

IndexedDB transactions in very old Safari (pre-15).

WASM features used in some validators (Safari 14 and earlier).

Troubleshooting steps

Hard reload (Ctrl+Shift+R).

Check the browser console (F12) for errors.

Try a private/incognito window.

Email support@certforged.com with the browser version and a description of what broke.
