I was a dedicated conkeror user until ~4 years ago and loved it. The webjumps were a pleasure to use, the Google I'm feeling lucky jump was a particular favorite. Having everything scriptable and being able to add my own specific functionality had great potential, I dug a bit but never really used the full power that I'm sure was available.

I started using conkeror after a shoulder injury that was being aggravated by mouse use, it was not particularly pleasant at the time but left me much more mouse-independent after I'd fully recovered.

I eventually left Conkeror because of a few hassles, I remember trying to set it as the default browser was not very simple, and just trying to get it (and XUL) installed and running would sometimes fail. This is a nice reminder though, I feel tempted to track down my old .conkerorrc and give it another roll.
