The connection was interrupted while the page was loading - Firefox - Firebase - signInWithPopup()
<p>I currently have a website that uses Firebase to authenticate users with facebook. I am using the Firebase JS SDK and signInWithPopup() method to authenticate my users. </p>

<p>The website works perfectly fine on Chrome, but when my users try to login with Firefox, they see the following error</p>

<pre><code>The connection to wss://s-usc1c-nss-104.firebaseio.com/.ws?v=5&amp;s=Tqa1ImoPipzRYUPJ8vnALN7Fjzda2roZ&amp;ns=my25pics was interrupted while the page was loading.
</code></pre>

<p>What are the possible reasons for this error and how or what would be the fastest way to fix it ? </p>

<p>Any help is appreciated. </p>

<p>Thank you </p>
