After playing with FF now I've decided to switch permanently and use Thunderbird as my mail client instead of Mozilla App Suite.
Pages were loading slowly until I remembered that the pipelining is disabled by default.
To alter these go to about
:config and type in "http" in the search box at the top, set "http.pipelining" to true by double clicking on it.
