1560723 - @yvrairport Wi-Fi captive portal login redirects to a 404 page in Firefox, but logs in successfully using Chrome

Status: RESOLVED WORKSFORME

(Core :: Networking, defect)

Description

[Chris Peterson [:cpeterson]]

I connected my Windows 10 laptop to the @yvrairport Wi-Fi network at the YVR airport. I tried to open http://neverssl.com/ in Firefox 69 Nightly and Firefox opened an unstyled, text-only captive portal page as expected. However, clicking the login page's "I Agree" button just redirected to a 404 page (with a URL path of /undefined like http://detectportal.firefox.com/undefined) and did not log into the network.

Loading the same page in Chrome redirected to a different captive portal login page (with a styled layout and YVR branding). Clicking this page's "Agree" button successfully logged me to the network.

I can't reproduce this bug a second time because the network recognizes my laptop, even after I disconnect and reconnect to the Wi-Fi. I don't know how to clear my captive portal login. Also, my flight leaves soon, so I won't be able to attempt to reproduce again later.

Here is my about:support info. I don't have TRR enabled.

Comment 1

[Mike Hommey [:glandium]]

Comment 2

[Chris Peterson [:cpeterson]]
