Currently I renovate my apartment because of technical issues with my home network. Today I will receive a big package with CAT8 Ethernet equipment. :) Used too old cables for my network... But 40GBit with CAT8 should be enough for the next 10 years. ;) I have narrowed down the issue: Firefox and Thunderbird requires currently a IPv6 connection. If this the router from the ISP only supports IPv4, these Mozilla programs are very slow. (Very slow startup and handling. I think I don't need to provide a list of the installed packages. There are no troubles with the packages. -- You are receiving this mail because: You are on the CC list for the bug.

When I disable IPv6 in my main router (LinkSys WRT33X) Firefox and Thunderbird are extremely slow. Tried to disable IPv6 in about:config. But doesn't help. -- You are receiving this mail because: You are on the CC list for the bug.

My ISP only (A1 Telekom/Austria) currently only provide IPv6 for business customers as far I know. Accidentally stumbled over this article some time ago - it seems IPv6 could be available also for A1 business customers: https://kofler.info/ipv6-eine-leidensgeschichte-aus-oesterreich/
