App Not Working on Some Browsers or Devices
Your app works fine on your browser (usually Chrome) but breaks on other browsers like Safari or Firefox, or on specific devices. Features don't work, layouts break, or the app doesn't load at all.
Common Causes
- Using browser-specific APIs not supported everywhere (e.g., some CSS features in Safari)
- JavaScript syntax not supported in older browsers
- Safari has stricter cookie and storage policies that can break auth
- Mobile browsers have different viewport handling
- WebKit rendering differences causing layout issues on iOS
How to Fix It
- Test on the broken browser — open the console (F12 or equivalent) for error messages
- Check Can I Use (caniuse.com) for any APIs or CSS features your app relies on
- If Safari breaks auth, check cookie settings — Safari blocks third-party cookies by default
- Add appropriate CSS prefixes for Safari (-webkit-) and Firefox (-moz-)
- Test on actual devices, not just browser dev tools device emulation

Get HelpFrequently Asked Questions
It works on Chrome but breaks on Safari. Is that common?
Very common. Safari has different CSS rendering, stricter cookie policies, and some JavaScript APIs aren't fully supported. AI tools typically test only on Chrome.
Do I need to support all browsers?
At minimum, support Chrome, Safari, and Firefox — that covers 95%+ of users. A developer can identify and fix the specific compatibility issues.
