Mozilla or Mozilla Firebird are the ones with the best features I know of with no ads (Firebird has no email or newsgroups built in)
other browsers are K-Meleon and Off-By-One...and I believe there is one based on IE called "Avast"

free email ..best I know of is Pegasus...it will do EVERYTHING once you get it set up like you want. There are others ..Foxmail I think still exists
