Download of large ISO-files is corrupt and have different sizes
When downloading larger ISO or ZIP files to our VDI clients (Windows 10) from VMware or Veeam, we get different sizes of the downloaded files and the checksum is incorrect (see attached image - yellow Chrome, orange Firefox). We used Firefox Version ESR 52.6.0 (64-Bit) and have updated it to 60.4.0esr (64-Bit) now, but still the same problem. When I use another browser (IE or Chrome), we do not have this problem. If I use Firefox 64.0.2 (64-Bit) on my local PC, it is working fine. Any suggestions?
