Wow, that was it. It is like having a completely new browser. Thanks!!
Can you give a "nutshell" summary of the difference between IPv6 and IPV4 so that I understand what I just did when I adjusted the about:config file?
In terms of any kind of short summary of differences between IPv6 and IPv4, that would not be possible in a few sentences or paragraphs as it is quite involved.
What you did in the Firefox config was to disable it from trying to resolve DNS hostnames by querying IPv6 DNS nameservers. If you were to disable IPv6 networking support on your box the time-out would occur very quickly, and fall back to IPv4 lookups before the connection timed out (in other words with no IPv6 on your box you would never have noticed this).
Most people have no support for native IPv6 connectivity from their ISP, so most people should disable it. Even so, the configuration change you made in Firefox is still recommended as it will completely skip the first DNS lookup trying to query AAAA records (IPv6) and instead go straight to A record lookups on IPv4. This enhances performance a smidgeon.

Is it possible that trying to resolve hostnames between IPv4 and IPv6 is also the problem with my Yast? It always times out when trying to refresh the list of configured repositories and when downloading packages that I have selected to install. I continue to have to hit the 'retry' button. My internet speed is so much faster now that I disabled IPv6. Is there a way to do that also in Yast?
