Hi, this is likely slow H3 upload speed (Bug 1708868).

We do experiment with a fix and would appreciate help in testing it. 

* Make sure you see the preference `network.http.http3.cc_algorithm` (Firefox Nightly 119 and onwards) https://www.mozilla.org/en-US/firefox/119.0a1/releasenotes/
* Measure the upload throughput while on the default setting (`1` for Cubic).
* Modify this preference to `0` (indicating newReno).
* Restart Firefox and measure the upload throughput again.
