i wouldnt reccomend gmx as it is very slow, and opens alot of new windows (not tabs) seemed to force a new window

I haven't found it slow, but agree about the windows. It's Java, I think, seems a bit overcomplicated, and doesn't work as well as it might with non-standard browsers like K-Meleon. However, all you have to do is set up GMX once, then pick up your mail by POP3 or whatever.
