firefox seems to be slower in 7.10 than 7.04

Asked by Bob Pearson

I have just upgraded from Feisty 7.04 to Gutsy 7.10 and both Firefox and my email (I use Thunderbird) seem to be operating much more slowly. I've checked my internet connection speed and it's about usual at 6.7Mbps, so that's not the problem. Has anyone else noticed this? Does anyone have a fix?

Disable ipv6 go to Applications->Accessories->Terminal and type
sudo gedit /etc/modprobe.d/aliases

Search and change the ipv6 row as below:
alias net-pf-10 off # ipv6
then add this row:
alias ipv6 off

To force not load ipv6 kernel module:
sudo gedit /etc/modprobe.d/blacklist
add this row:
blacklist ipv6

Reboot your pc.

To increase Firefox speed try this little http://www.elart.it/mozilla/speedup.php

Then you can play also with:
your DNS servers address setup by change them and putting the OpenDns server
and/or try to find best MTU setting for your connection.
