If anyone seeing this performance discrepancy can help test out a hypothesis, it would be appreciated.

In bug 1851908, we just introduced a preference named `network.http.http3.cc_algorithm`, which can be accessed through `about:config`. This preference exposes the congestion control algorithm employed for HTTP/3.

Please follow these steps:

    Make sure you see the preference `network.http.http3.cc_algorithm` (Firefox 119 and onwards)
    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.
