Coincidentally -- I tested Nitroflare later that day and I was able to access through one single multihoster.
JamesBrown - You said the issue was only on web-browsers. In this case I'm assuming you're downloading directly, not through a multihost. Based on your specific issue, can you try two things:
(a) clearing your browser cache/DOM storage/etc?
(b) Also try accessing from an "incognito" session.
The incognito session suggestion is only temporary just to diagnose the problem / assure it's not an extension issue (assuming you have extensions blocked in incognito). You won't have to access using this method in the future; it's simply a test.
