Disabling IPv6?!

This is an... opinionated list. Wish there was more annotation around what those opinions were.

Don't know if it is still true. DNS lookup didn't work correctly when ipv6 was enabled.

W..what? I don't think this has been true for any Firefox version, ever. Certainly I'm using v6 right now. (Not on hn of course, it's v4 only)

It was true for a Linux + Firefox combination a few versions ago. I had that issue.

Basically, the DNS lookup lasted like 4-5 times longer than it did while opening the same site in Chrome.

It used to be issue - in your local network, you had IPv6 automatically with Vista and newer (the same for Linux distributions). So your browser resolved AAAA records, trued o open connection to the the host, after few seconds found out that it is going nowhere, resolved the A records, the site worked.

So it became popular to manually disable IPv6 to speed up the browsing.
