Hello. I'm using Firefox 78.0.2 on a 64-bit PC. I have Cox an an ISP, with a fiber install for 500 down/up. When I use speedtest.net and Fast.com, I only see speeds of 40 down, .8 up; very slow. I've also monitored the traffic up/down on my router, and Firefox seems to be acting like it's limiting through-put to speeds not even close to what is being offered by the ISP. When I use speedtest.net or Fast.com on Edge, Chrome, or other browsers, I see speeds consistently over 400 Mbps down/up. Can anyone think of reasons why I can't get these same results on Firefox which has been my preferred browser? Thanks! Bob

Additional info: I've pursued a fresh install of Firefox, with no change. Proxy setting uses system settings (same as other browsers on the PC).
