Description

2 years ago
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160715064235

Steps to reproduce:

I could not reproduce it on will, but scenario where it often happened:
Slow internet connection
Many (~8) tabs open
Open a heavy pdf or a big website where it slowly loads all content but does not show it yet but a loading icon in the middle of the page
Get back to a previously loaded tab.


Actual results:

In the previously / already loaded tab it also shows a loading icon in the middle of the page instead of the contents from cache. When the new tab finished loading shortly after the previously loaded tab will also show it's contents.


Expected results:

Directly show contents.

I tried to reproduce it with a nodejs script, which I run locally and then open another page but with this approach tab loading worked fine:

const http = require('http');
const https = require('https');
const express = require("express");
const app = express();

app.get('/test.html', function (request, response) {
	var id = setInterval(function() {
		response.write('Hello<br>');
	}, 10);
		
	setTimeout(function() {
		clearInterval(id);
		response.end(' World!');
	}, 20000);
});

var server = http.createServer(app).listen(8889, function () {
	var host = server.address().address;
	var port = server.address().port;

	console.log('Server listening at ', host, port);
	console.log('CTRL + C to shutdown.');
});
Hi,

I don't quite get if this is still a bug or not?
If yes please provide an example which you used for reproducing this issue.
Can you please test again in safe mode?

Hi, the bug still occurs but very, very occasionally. I will not be able to reproduce this bug on will and therefore recommend to close the report?
