I'm not sure what MTU is.
Max Transmission Units, a setting in your router:check your ISP site for their recommended settings.

Also, hunted around for things I have done to speed up FF in the past.

Type about:config into the firefox address bar.

Use the filter to search IPv6, and set network.dns.disableIPv6 to true

(bearing in mind that IPv6 is coming sometime soon...maybe..)
