If it works under edge and not Firefox, I think we can safely assume it's a setting somewhere in Firefox causing the issue.

Not quite a safe assumption, I think it's more likely the Firefox cache is corrupt than a user setting is misconfigured. (Apologies if you meant 'setting' in the broadest sense, which would include cached system settings.)
Four possibilities:
- the browser itself is responsible (very unlikely);
- a browser configuration setting is wrong (unlikely);
- the browsers cache of remembered working parameters, cookies etc, is corrupt, accidentally or by malware (possible);
- or it's something completely different, like a Router fault, (also possible).
Edge, Chrome and Firefox etc. each have their own cache so using a different Browser also uses a different configuration and memory. Depending on the cause, especially if malware is the root, they may become corrupted too.
One example how a bad cache causes this sort of problem. When a Browser connects to a server it sends a mass of information about the client, like the browser name, operating system, available plugins and versions thereof. The server uses the information to adapt web pages to the user device, which could be a Mac, or a SmartPhone, or a PC. Either the server or the client can bail out when an inconsistency is found, or results are undefined. (In computer-speak an 'undefined result' can be anything between apparently normal operation and a crash – all bets are off.)
Frequently used information is often cached to improve performance. It can be remembered between sessions and reboots. If an upgrade is applied and the cache isn't updated correctly, then the resulting mismatch between client and server is liable to cause peculiar errors. Completely emptying the cache forces the Browser to repopulate it from scratch, with luck fixing the weirdness. In the other thread I provided a link to a site explaining how to clear Firefox's cache. It's worth trying. As is powering off the router for at least 20 minutes, which should force it to refresh as well.
Raymond has hinted he may not have a fast Internet Service with no-download limit. As I know to my cost upgrades that misfire due to network problems cause havoc.

Dave all cache are set to clear out on shut down and I had done a full clear out not long ago myself. This leads me to consider if the cach has been cleared at my end the serve is not then recognising what it needs to? Or the updates of all and sundry have caused a hick up as so often happens in one week Microsoft, Firefox, Adobe Reader (Not Flash) a couple of other products.
Thanks Dave re browser cache.
One thing I have considered in all this is in our area atm is the instal of whats known here as NBN the latest greatest, fast internet cabeling RRFLMAO. This is to the Node I am furthest house away still using copper not fibre optic and still on ADSL2. Those who do have NBN are complaining about drop outs, speed as slow as snails race and more.
Dave the fact server cache also become corrupt I have found in the past also causes major problem anything from sign in to being able to view uploaded files by individuals. Server updates, server Re-sets, server memory faults, server router faults.
Add to that software updates across the world poorly written software, app's etc etc and I do include Firefox which I have been using since it was originally Netscape. 
ISP speed check during these last few days resulted in 13mbps tops download far worse for upload. The new NBN I should get top of 50mbps.
I freaked out when I saw my daughter down in Sydney is getting 1000mbps and she's in a rural area I wish is all i can say. In the whole are top speed here is 100mbps and were are a city with in 40 mins of Brisbane.
