My Firefox 4 often became unresponsive for 3-4 seconds. Just today I finally nailed the cause - Mozilla's own Open Web Apps addon. After disabling it everything flies again :-)
So it's not only about startup time. My desktop computers (and so Firefox) usually run without restarts. I really hope that Electrolysis (out-of-process stuff, now implemented only for plugins like Flash) for addons will make finding bottlenecks far easier.

EDIT: It seems the Mozilla plan is not to have each addon in a separate process: https://developer.mozilla.org/en/Jetpack_Processes
