Supported browsers

Rainbow Tour Guides works in current versions of the major browsers. We don't maintain a strict minimum-version list — the rule of thumb is: if your browser updates itself regularly, you're fine.

Recommended browsers

• Chrome
• Safari
• Firefox
• Edge

Keep whichever one you use up to date (see The site isn't working on my phone or browser for how to check). JavaScript and cookies need to be enabled — the site won't function without them.

The most common surprise: in-app browsers

If you tap a Rainbow Tour Guides link from inside Instagram, Facebook, WhatsApp, or a similar app, it usually opens in that app's own built-in browser rather than your phone's regular one. These in-app browsers often can't complete sign-in, the security check, or Stripe checkout, even though the rest of the site looks fine.

How to open it in your real browser:

1. Look for a menu icon (usually three dots, or a share icon) in the in-app browser's toolbar.
2. Choose Open in Chrome, Open in Safari, Open in browser, or similar wording.
3. If there's no such option, copy the link and paste it directly into your phone's browser app.

Quick fixes if a page still misbehaves

1. Confirm you're in your device's actual browser app, not an in-app browser.
2. Update the browser to its latest version.
3. Reload the page.
4. Try a private/incognito window to rule out a stuck extension or cache — see The page is blank or broken.
