Saka Key is beautiful when it comes to the options interface and it is so easy to modify and set keyboard shortcuts. I was using Vimperator, but all I wanted from Vim was the ability to open a link from the keyboard. And Vimperator is dying (or dead). Saka Key is beautiful when it comes to following links.

My only negative is: it took me forever to FIND saka key. Searching in FF addons with "link" and "follow" got me nowhere. Finding this addon should be easier, because it is super!
