Limited to macOS? Does not reproduce in FF 141 and 142 on Windows.

It reproduces for me in FF 142 on Windows. When I first went to https://cloudflare-quic.com/ it said HTTP/3, but after a few hard refreshes it says HTTP/2 and hasn't gone back to 3

Oh, I see - hard refresh consistently shows HTTP/2 but after one or two soft refreshes it becomes HTTP/3 for me until next hard refresh.

Edit: it is always second soft refresh for me that starts showing HTTP/3. Computers work in mysterious ways sometimes.

		I restarted FF and am now seeing something similar. Hard refreshing alternates between 2 and 3, and soft refreshes quickly get back to 3 most of the time

For me (FF nightly on Linux) a hard refresh has a roughly 50/50 chance of choosing HTTP3 or HTTP2.

No, I have also observed it in Firefox (via Flatpak) on Fedora Linux 42. When I filed the original GH issue that webcompat-bot turned into this Bugzilla item (https://github.com/webcompat/web-bugs/issues/168913), my full report didn't make it into Bugzilla.
