Yeah, it's started growing on me once I learned about what's possible via extensions. At some point as long as they expose the APIs to build the right thing it stops mattering to a degree how the defaults work. Witness things like Conkeror (http://conkeror.org http://conkeror.org) being built initially as a Firefox extension due to the fact that all the extensibility to build a better UI was there from the start.
