Same problem with a Fortigate, disabling SSL inspection bypass the issue.

This seems like a regression: Firefox 128.4.0esr and Firefox 133 are working fine. Only Firefox 128.5.0esr seems to be affected.

in testing I found that
on 128.4 network.http.http2.allow-push is set to 'true'
on 128.5 network.http.http2.allow-push is set to 'false'.
I changed it back to 'true' and restarted Firefox and tried again and it is working again.

Works for us too

I think the issue is that I forgot to request uplift for bug 1919750 to ESR along with the H2 Push disablement.

Depends on: 1919750

Thank you for the reports, we are preparing an esr128.5.1 dot release with a fix. We are aiming to rollout tomorrow 2024-11-29.

I have a build running with the fix here
Would you be able to test if this works even with allow-push=false?

Thanks!
