FF is having MAJOR issues, eh? I paid my money a few years ago and have enjoyed unlimited from them; I more than got my money's worth. All the same, it seems that whatever super duper upgrade, reformatted website, with completely retooled,...well,...whatever TF they did...they can't stay up. Crash after crash. My guess is that they've shot themselves in the foot for the time being. Meanwhile, many are scrambling to whatever the next best is. Be it We, Mega, Swiss, even Google. They all have, by today's standards, severely limited storage for those such as myself that prefer to upload stuff and leave it there indefinitely, unless of course you subscribe and pay. For myself, Google is the easiest. But again, it costs for a large (2Tb) yet still finite storage.
My hope is that FF figures it out and pulls ahead. I have low confidence that FF will prevail, though.
