Iceweasel slow
 

My Iceweasel are slow. who knows any thing to put iceweaseal mor faster.

Mine works fine. You must be doing something wrong.

Maybe try using swiftfox ? it's nearly the same, but it's faster..
Yeah I know nearly makes a great difference ;-)

swiftfox is no faster. Iceweasel IS fast. If its not something is wrong with your system.

Try turning IpV6 off. Type about:config in Iceweasel's address bar and look for network.dns.disableIPv6 right click the value and change it to true.

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20061205 Iceweasel/2.0.0.1 (Debian-2.0.0.1+dfsg-1)

Does this also speed up Firefox and other mozilla clones?

yes it does

If the option is avalable in the about:config page then it would.

Iceweasel as far as I know with its differences is really just its name and logo / icons and maybe some slight tweaks with the .deb packaging. Its really just a fork of Firefox due to licensing issues with the name and logo of the firefox browser and Debian's stance on FOSS.
