When I wrote that tutorial at that time port was allowed in app domain. And I actually able to run app with 81 port (wamp server). Now it looks that facebook is not allowing port in url. You can use <code>localhost</code> in app domain. 
I will update information as soon as possible. I am trying to find out solution.
 

A temporary solution is use localtunnel <a href="http://progrium.com/localtunnel/" rel="nofollow">http://progrium.com/localtunnel/</a>

This is what I used to do.

If you are using Windows, you need to modify the host file. Host file location will be at <code>%SystemRoot%\System32\drivers\etc\</code> 

Add a new line in host file like this

<pre><code>127.0.0.1 localhost.YOUR-SITE-NAME.com
</code></pre>

Save the host file. 

Go to FB apps setting control panel and give <code>localhost.YOUR-SITE-NAME.com</code> in Apps domain field. Save changes.

Now load you local environment like <code>localhost.YOUR-SITE-NAME.com</code> from your browser.

NB: change YOUR-SITE-NAME with your domain name.

<li>A new tab will open. On that tab, scroll down to the section, "Tell us about your website" and again enter <code>http://localhost:8080/</code> for the Site URL.</li>

I develop locally and I use this URL: <code>localhost/fb</code>

Then I had to add a website with the following URL: <code>http://localhost</code>

Under App Domains I added <code>localhost</code>.

Now it works. The only issue I had was, that you have to use this URL in all of your scripts. E.g.

<pre><code>$loginUrl = $helper-&gt;getLoginUrl('http://localhost/fb/login-callback.php', $permissions);
</code></pre>

You can't use <code>127.0.0.1</code> here ...

2018 working solution

It took me ages to figure this out, so I'm going to share my solution.

I tried all the suggested answers, but nothing worked for me, and in the end all I had to do was to go to <a href="https://developers.facebook.com/apps/YOUR_APP_ID/fb-login/settings/" rel="noreferrer">https://developers.facebook.com/apps/YOUR_APP_ID/fb-login/settings/</a>, and add my full callback url in the Valid OAuth redirect URIs box. 

In my case, using ruby on rails, my url looked like this <code>http://localhost:3000/user/auth/facebook/callback</code>.

And right after I added it, everything started working! Hope this helps someone else facing this issue.

Working solution (August 2018)

First, select your app in the <a href="https://developers.facebook.com/apps" rel="nofollow noreferrer">developers dashboard</a>.

Then make sure your app is in <a href="https://developers.facebook.com/docs/apps/managing-development-cycle/#step1" rel="nofollow noreferrer">development mode</a>, as it allows localhost over HTTP. To do so, click on the toggle situated at the top right of your app's page.

Finally, please follow the notes below as they could cause trouble if improperly filled:

<ul>
<li><code>Settings &gt; Basic &gt; App Domains</code> should be empty</li>
<li><code>Products &gt; Facebook Login &gt; Settings &gt; Valid OAuth Redirect URIs</code> should be empty</li>
</ul>

blocks|key|208150|text|我尝试了这里提到的所有解决方案，但都没有奏效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|208151|解决了我的问题的是将"OAuth重定向URI“从firebase复制到”有效的OAuth重定向URI“。|208152|我把所有的域名都留空了|208153|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I tried all the solutions mentioned here but none of them worked. 

What solved my issue was copying the "OAuth redirect URI" from firebase to facebook app "Valid OAuth Redirect URIs"

I left all the domains blank

I tested this and it works for me [Feb 2020]:

<ol>
<li>Install ngrok &amp; get your https url (example: <a href="https://a3asdf23.ngrok.io" rel="nofollow noreferrer">https://a3asdf23.ngrok.io</a>)</li>
<li>Go to FB App Dashboard Settings (Basic) -> under App Domains -> add <code>https://a3asdf23.ngrok.io</code>, <code>https://ngrok.io</code>.</li>
<li>On the same page, scroll all the way down, Add Platform (Website), set the url as <code>https://a3asdf23.ngrok.io</code>. Not finish yet, click QuickStart -> under "Tell us about your website", put the same url <code>https://a3asdf23.ngrok.io</code>.</li>
<li>Then go to Products -> Facebook Login -> Settings -> Client OAuth Settings -> Valid OAuth Redirect URIs -> add these <code>https://a3asdf23.ngrok.io</code>, <code>https://ngrok.io</code>, <code>https://a3asdf23.ngrok.io/{your-redirect-uri}</code>.</li>
</ol>

And here you go. Thanks me later :)

From a tutorial here: 
<a href="http://ankurm.com/blog/api/using-localhost-for-facebook-app-development/1091/" rel="noreferrer">http://ankurm.com/blog/api/using-localhost-for-facebook-app-development/1091/</a> 

I tried to set up a Local development Area for my Facebook app. But when I put "<a href="http://localhost:85/my_app/" rel="noreferrer">http://localhost:85/my_app/</a>" as my domain name, Facebook says 

<blockquote>
 App Domains: "<a href="http://localhost:85/app-name/" rel="noreferrer">http://localhost:85/app-name/</a>" should not contain protocol information. 
</blockquote>

Also when I put "localhost:85/my_app/" as my domain name, I get the error: 

<blockquote>
 App Domains: localhost:85/my_app/ is not a valid domain.
</blockquote>

来自这里的教程：我试图为我的Facebook应用程序设置一个本地开发区。但是当我把"“作为我的域名时，Facebook说应用域名："“不能包含协议信息。另外，当我把"localhost:85/ my _app/“作为我的域名时，我得到了一个错误：本地应用程序域：：85/my_ App /不是有效的域。
