Firefox seems to Limit Speeds to 300Mb/s when using any other website besides speedtest.net
Hi, I have a 1Gb/s symmetrical fiber. And when testing Google Chrome and Firefox, Firefox has a problem with uploading to most sites. But somehow it does with Speedtest.net. It's kinda weird tbh. Not to mention I have QoS enabled why the 600 and 700.

Forgot to mention that second image is Google Chrome Speetest while the first is Firefox Speedtest, and the last from speetest.net is from Firefox.
Boot the computer in Windows Safe Mode with network support to see if that has effect.

I get no Networking when going into safe mode with Windows 11. So safe mode won't work at all. I selects Safemode with Networking too. F5. So idk.

Can you test it by setting network.http.http3.enable = false in about:config and restart?
