I love Vimium too! (using on chrome) Took me a while to learn all the shortcuts (thanks Anki!), but that was worth it. Wish it was more integrated to the browser though (having to wait for a page to finish loading before I can use a shortcut is sometimes annoying).

You're not mentioning my favorite Vimium command! m<key> to save a mark, and `<key> to load it. lowercase chars marks are in-page marks, and uppercase chars are global marks (like bookmarks).
