CAPTIVE PORTAL DETECTION

Firefox Firefox Last updated: 10/11/24 49% of users voted this helpful

Firefox's captive portal detector tests whether the network connection requires
you to log in or accept the network's terms before permitting you to use the
network. This is most often the case when using a public Wi-Fi hotspot, but it
can also be a corporate guest network that prompts you to agree to its
acceptable use policy. To learn more, see Captive Portal Detection in Firefox
Source Docs.

CAPTIVE PORTAL CHECKS

Firefox tests if the connection is a captive portal by regularly connecting to
http://detectportal.firefox.com/canonical.html. Firefox will also make
connections to this URL to check if your current network supports certain
technologies such as IPv6.


WHAT TO DO AFTER THE CAPTIVE PORTAL CHECK

If the page was left open by Firefox, you may simply close it.

If this happens frequently, please file a Networking bug and describe your case
(requires creating a Bugzilla account).


HOW CAPTIVE PORTALS WORK

Most captive portals redirect you to a login page or a page where you must agree
to an Acceptable Use Policy (AUP). Firefox will make automatic connections to
detect these redirects and will notify you by indicating that you may need to
log into the network. After doing this, the tab should be closed automatically
by Firefox. Occasionally, it will be kept around to display a message from the
network's owners.
