Once in a while I've been getting "Server not found" errors from Firefox that surprise me. The links are to real sites. Other browsers can see the site. I thought that the problem might have to do with some tightened security rules. No, the problem is IPv6. I don't have IPv6 at home. But Fedora has it enabled normally. This generally doesn't cause problems. But now it has.

Fix: <https://support.mozilla.org/en-US/kb/server-not-found-connection-problem?redirectlocale=en-US&redirectslug=Server+not+found#w_ipv6>

type URL "about:firefox"

firefox ver 50.0 about:firefox = The address isn’t valid

about: works, and is what I always used. -- Len Sorensen
