Windows Azure – Firefox & “Port Restricted for Security Reasons”
April 12th, 2009 Posted in Development
I’ve been starting to delve into the world of Windows Azure this week.
After getting the Azure Samples loaded, I tried running one of them (just by hitting F5 in VS) and, as Firefox is my default browser, got a “Port Restricted For Security Reasons” error.
Of course, it worked fine in IE
Here is what to do –
It turns out, that my application was trying to use port 87 on 127.0.0.1 (127.0.0.1:87)
Load up Firefox. Type about:config in the address bar, and hit enter. You will get something like the following:
Right click, and click New -> String.
Set the preference name to: network.security.ports.banned.override
Next, set the value to: 87 (or whatever port your app is using)
Done!

This is nowhere near good enough. I can only unban one port at a time? And I have to go through Mozilla’s version of the registry to do it? And even then it’s JUST NOT WORKING? Screw this blatant censorship and steering of users away from content by Mozilla.

each to their own i suppose….
You don’t have to do this frequently, only for high – risk ports like this…

Thanks Alex,
that port blocking was one of those things that was mildly annoying (a reload would work), but finally frustrated me. Much appreciated!

Alex, this little issue was getting me down while I was trying to debug my first Azure app in Visual Studio 2010. Thank you for providing this tip – it was a real timesaver!
