Firefox 130 connection issues

[rofferom]

I have difficulties to connect to wtransport, using Firefox 130 and wtransport 0.3.1.

I have seen in #166 that there has been a recent fixup regarding Firefox support, however I have various behavior, depending of the OS:

• Linux (Firefox 130.0.1): I have few connection issues
• Windows (Firefox 131.0b8): I can't connect
• macOS (Firefox 130.0.1): I can't connect

Some extra notes

• I have no connection issue when using Chrome 128.0.6613.137.
• I'm not using serverCertificateHashes because it seems not to be supported on Firefox. Instead I'm using a Let's Encrypt certificate

Here are some logs

Still not able to reproduce (on Linux 130.0.1).

I'm not using serverCertificateHashes because it seems not to be supported on Firefox. Instead I'm using a Let's Encrypt certificate

BTW, serverCertificateHashes is supported on Firefox since version 125: https://caniuse.com/mdn-api_webtransport_webtransport_options_servercertificatehashes_parameter

I reproduced the issue more than 5 times in a row with Firefox 131.0 on Linux vs wtransport 0.4.0, actually I never managed to connect. But I have no issue while running examples/full.rs. I'm going to check the differences with my integration of wtransport.

About serverCertificateHashes, I wasn't sure of the actual support in Firefox, I previously had some errors that seemed to be related to it. Since it seems I have another issue, maybe my interpretation of the real issue I was facing was wrong. I'm going to continue to use serverCertificateHashes for this issue
