workaround for Port restricted for security reasons

more options

I was trying to sign into a restaurant's guest wifi, but the login page used a restricted port, and I got an error page with the message: "Port restricted for security reasons"

I'm on Firefox nightly, and this article https://support.mozilla.org/en-US/questions/1083282 mentioned a setting to get around it using network.security.ports.banned.override in about:config, but I didn't see it in the current version.

Is there any way to work around this? Thanks!

Hi About:config is available in the Beta and Nightly versions of Firefox for Android from the Google Play store.

Sorry, I don't have an issue accessing the about:config page on Nightly version Firefox for Android 91.0a1 (Build #2015815755), my question is about the network.security.ports.banned.override setting in about:config which I could not find. Any help on working around the "Port restricted for security reasons" page preventing me from logging into certain wifi network would be appreciated.

Some preferences are not listed by default, they need to be added if you want to customize them. Tap the + button to the left of the search box, type or paste the preference name, change Boolean to String (assuming that is a String preference), enter an initial value, then click Create.
