Why am I seeing captive portal request on my home network?

have suddenly started getting prompts on my 2010 Mavericks MBP (10.9.5) every five minutes that bring up a page with HTML like the following:

<HTML><HEAD><TITLE>Success</TITLE></HEAD><BODY>Success</BODY></HTML>

At the bottom of this modal window is a url:

http://www.apple.com/library/test/success.html

I am on my home network which uses an Airport Extreme running 7.6.4. I Ran the latest update this evening. Updated Firefox. Did not make any known configuration changes to either my computer or my network. Why am I suddenly seeing this page, which other posts suggest is a captive portal test?

I saw another question that demonstrated how to disable the Captive Network Assistant, but as I do take my computer to hotels that use these portals, I'm reluctant to jump straight to that. Instead, is there something on my Airport that is generating/blocking these all of a sudden and it shouldn't be? I tried a factory reset of the Airport and I'm still seeing this issue.

How can I configure my network so I stop getting these annoying popups?
