1760932 - about:config does not allow new entries

Status: RESOLVED INVALID

(Core :: Networking, defect)

Description

[Bill Zaumen]

Attachment: AboutConfig.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:98.0) Gecko/20100101 Firefox/98.0

Steps to reproduce:

I entered the about:config URI and got to the appropriate page. I wanted to modify network.security.ports.banned.override to allow ephemeral ports. That property was not there, so I right-clicked on the page

Actual results:

I got a pop-up menu with the entries Save Page As, Select All, View Page Source,
Inspect Accessibility Properties, Inspect (Q),, NoScript.

Expected results:

Based on several web pages, there should have been a menu item containing the
word "New", which would let me add the entry.

Until very recently, this was not an issue: I could use ephemeral ports with firefox. I have a couple of Java applications that start a web server on either a specific port or an ephemeral port and then open a browser with an appropriate URL. This is either to run a web-based application or display on-line help in a browser.
