donors.vitalant.org - Firefox is an unsupported browser

[webcompat-bot]

URL: https://donors.vitalant.org/dwp/docs_ext/en_US/not_supported_mob_browser.html

Browser / Version: Firefox iOS 34.2 Operating System: iOS 14.6 Tested Another Browser: Yes Safari

Problem type: Something else Description: Firefox on iOS unsupported on this ‘vitalant.org’ blood donation login portal. Steps to Reproduce:

1. Go to https://vitalant.org.
2. Press login button at top right.
3. Enter zip code (70506 in my case) and continue. I guess different zip codes means different portals, so you may need to test with my zip.
4. The page will reload, then click login button again on latest iOS Firefox browser.
5. The login portal tells you that Firefox is not supported - only Safari and Chrome for mobile.

Additional:

• App icons look like they are from 2010.
• Using iPhone 11 w/ iOS 14.6 and latest Firefox default browser.
• Remember Apple forces all 3rd party browsers to use the webkit engine, so this is technically a Safari browser… but regardless the page error is way out of date and wrong.
• Tested on Windows 10 Firefox (gecko) and works fine. I was able to schedule on the portal when switching to my Safari browser on mobile yesterday as well.
• A lot of Android users use Firefox mobile (gecko) and probably get this same “false” error.

We appreciate your report. I was able to reproduce the issue. Firefox is an unsupported browser:

Notes:

1. Reproducible regardless of the status of ETP
2. Reproducible on the latest build of Firefox Nightly
3. Works as expected using Safari:

Tested with: Browser/Version: Safari 14.6/ Firefox Daylight 35.0 (5448) Operating System: iOS 14.6

Moving this to NeedsDiagnosis for further investigations.
