Only issue on FF is the international download speed issue on tcp. Everything else I had no issues and no downtime since I got connected in july.
Yup, single threaded from international is always slow for some reason, I always have to set up multi-stream with FDM then I get 3MB/sec+.
All of my streaming is always perfect though, and that's probably 90% of my usage, besides normal browsing, so happy customer.
