Hello, That is what I was thinking as well. Why try and connect to it if there is nothing listening to that location?You can ping it with either the hostname "localhost" or the 127.0.0.1 just to make sure your network card and software is working and in fact that is part the troubleshooting process I learned while takingCisco courses.
Yes, install something on that local machine such as a MySQL server, Tomcat, or Apache and then in your browser type the address in with the port number. PHP LAMP or WAMP instructions in fact tell you to do that when you are done.
thanks,Greg

Are you running a local web server on port tcp/80/443, otherwise why connection to localhost? You need a server like apache, nginx, or whatever web server listening on 80/443 for a browser to find a webpage on localhost, which is your system. Otherwise the browser won't find a socket to connect to let alone a web page, which is what it's telling you.
## this will show you anything listening locally on http|https ports and what app did it
sudo ss -tpl | grep http
## try to connect if you think you should see an open socket from above, below fails
[~]# telnet 127.0.0.1 80
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
No active firewall right?
If you wanted to you can limit host access to bind external sockets like 80/443, or whatever to only 127.0.0.0/8 meaning only local processes can access sockets, not even someone on your local lan. This is a security practice in application cases for high-speed caching or inter-process communications local to this system only.

the browser shows the error as:
The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I need to specify a port. Cool. That's all I needed to know.

Regarding the original question of why the browser is saying "problem with address", what is the actual error? Name resolution, connection, cert, etc etc? Those friendly human readable errors leave too much open to interpretation.

The IP address range 127.0. 0.0 – 127.255. 255.255 is reserved for loopback, i.e. a Host's self-address, also known as localhost address. This loopback IP address is managed entirely by and within the operating system.
Thanks,
Alexander.

The local loopback mechanism may be used to run a network service on a host without requiring a physical network...

Are the addresses for localhost 127.0.0.1 and 127.0.1.1 ? That was a rhetorical question. What isn't rhetorical is why, when I enter either of those addresses into a browser , do I get a 'problem with address' page? Are there
