Didn't have issues with the starting the trial on FF 61 Beta, with uBlock and Privacy Badger enabled.

The service looks fairly good, but the speeds are not impressive. It looks Azure is used (and you can test your speed on it here http://www.azurespeed.com/Azure/UploadLargeFile)

Just to be clear we are not just using the default Azure setup. We have our own proprietary TCP acceleration technology in use on the Azure network and have 9 servers globally enabling acceleration. This test just shows you regular upload to Azure not a routed upload through our network.
