You are on ADSL i'm guessing? (which is quite often tunnelled leading to MTU problems).
Did you try lowering the MTU or checking your ICMP filtering as I had suggested in my earlier? (I didn't get any feedback on whether you had tried this suggestion). If you have a ADSL router box, you may want to check what you have your ICMP filtering set to in its firewall settings. 1. Do you have any ICMP filtered in your firewall router? or firewalling enabled on your machine? 2. Have you tried lowering your MTU? e.g. ifconfig etho mtu 1400 3. Also see if the MTU can also be configured/lowered on your router box 4. Try disabling path MTU discovery: echo 1 >/proc/sys/net/ipv4/ip_no_pmtu_disc Edwin Lee wrote: > The strange thing is that for whatever reason, this problem did not > surface before Thursday, but i did not do anything to Firefox (install > extensions, etc) recently.
