When I run https://fiber.google.com/speedtest/ or 
https://www.speedtest.net/ in Firefox - they show ~400Mbps download 
speed, and ~25Mbps upload speed.

Same websites, when run in Chromium, show ~50Mbps download speed, and 
~25Mbps upload speed.


Something appears to be wrong with Chromium that it doesn't show the 
real speed.

Anybody has an idea what might be wrong?


Sorry for this being potentially off-topic here. I couldn't think of any 
other forum where to ask this.


Thanks,

Yuri
