Unknown protocol error should not be alerted by turning whole page into error page

Details
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0
Steps to reproduce:
(On desktop or Android)
Visit some webs that both show the content and try to open that content in their own app by automatically navigating to uri like 'their-protocol://xxxxxxxxxxxxxxx'.
Actual results:
If the app is not installed so that protocol is not registered, the whole tab turns into an error page:
Problem loading page
The address wasn’t understood
[Try Again]
That makes user can't read the content neither on web or in app. The web is actually already showing the content, which firefox is blocking user to read.
Expected results:
Don't turn the whole page into error page. Alert unknown protocol error by dialog or something that won't override the tab, like other browsers do.

If the issue persists feel free to re-open this issue or file a new one with more detailed steps.
Hi Andrei,
Sorry for late reply.
Many apps register their own protocol scheme. Apple has itms://, itms-app://, Telegram has tg:// etc.
As for browser behavior, we can try open this html file in Firefox and other browsers:
<html><head><script type="text/javascript">
setTimeout(function(){
window.location="myapp://my-path-to-this-content";
}, 2000);
</script> </head>
<body><h2>
Hello.<br>
If you are using Firefox, this web is usable for only 1 sec.<br>
If using other browsers, you will see a popup in 1 sec and this web is always usable.
</h2></body></html>
After Firefox's error page override the page, I tried to click go back button, it went back and then soon the error page overrides the page again.
Everytime I have to switch to other browsers to view such webs.
Although it's bad for a web to navigate like that, but there are really some websites doing that (I can't remember them now. I'll post it here if some day I find them again).

I was able to reproduce this only on release using your steps.
On Nightly and beta however it didn't redirect me to an error page. It just showed the message.
Setting a component for this enhancement in order to get the dev team involved.
If you feel it's an incorrect one please feel free to change it to a more appropriate one.
