Firefox 29 is blocking ports for an application we run. When I try to use the about:config method to override the ban it has no effect. How can I open it?
I have followed the previous recommendations to create a user entry in about:config network.security.ports.banned.override;9581
This is still not allowing the web application access. This is a demonstration web application that we use daily.

Hello,
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
(If you're using an added theme, switch to the Default theme.)
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
Thank you.
Hello jameswj3, try with comma :
network.security.ports.banned.override, 9581
otherwise do it in user.js
user_pref("network.security.ports.banned.override", "9581");
thank you
