So i've recently switched from Chrome to Firefox and apart from the learning curve, I've noticed some performance differences. Mainly, when I go on https://ipv6-test.com/, I see the "Performing a TLS handshake to..." for quite a while before the page loads completely. Not only that, but the results are always inconsistent, with IPv4 test failing, sometimes IPv6 and "DNS4 + IP6" constantly failing. Tried disabling Tracking Protection, Addons, checking for advice but nothing. Tried different ipv6 test sites and see the same inconsistencies. Chrome never had this issue tho.
