This has nothing to do with the firewall nor SQL Server Browser services. By default SQL Server is going to listen on port 1433 unless you change it. If the port was blocked, you would not be able to access the instance.
SQL Server browser listens for incoming requests, again, if disabled, you would not be able to connect remotely to the server.
The status bubble is caused by a permissions issue. Easy way to troubleshoot, close Management Studio, right click, it and run as administrator. If the status shows up, you have a permissions issue.
