Chrome numbers are from Dec 2010 as compared to June 2011 in case of Firefox. I don't think it's valid comparison.
Same here. I believe they have a different "calling", Chrome is meant to be fast,light and simple.
Firefox feature-heavy and complex, a sort of web swiss knife.
While they are evolving towards implementing each other's strengths (Firefox more streamlined, Chrome more feature-laden) they kind of stay true to their origins.
I tend to use Chrome a lot more, but I always keep Firefox installed and updated as well.

We’re very excited to report that 85% of Firefox 4 users have chosen to install an add-on — that’s more than 60 million users every day! This number doesn’t include Personas, and even excludes popular add-ons bundled with other software that the user hasn’t actively agreed to install.

When we first saw this number, we expected it to drop as more and more users upgraded to Firefox 4; remarkably, it has stayed between 89% and 85% since launch in March. It’s also interesting to note that on the weekends when Firefox (and Internet) usage slumps, the percentage of users with add-ons increases, indicating those who browse on weekends are more likely to have customized Firefox.
We’ve also learned that on average, users have 5 add-ons installed, with the following distribution:
