I just installed the latest Firefox as part of download day.

My first thoughts (I haven’t looked at ff3 since and early beta…)
- I miss my bookmarks that all got deleted (meh.)
- I miss(ed) firebug. (getfirebug.com v.1.1 v.1.2 works just fine)
- I miss(ed) firecookie (http://www.softwareishard.com/blog/firecookie/firecookie-05-beta/ v0.5 seems to work fine)
- Firefox no longer crashes fatally every time I close it. (seriously, every single time I closed it)
- Startup and shutdown are INCREDIBLY fast compared to ff2.
- I miss my themes… and mozilla.org is a little swamped right now, so I can’t get a new one. However, the default theme is really not bad at all.. I just miss my old one.

We’ll see how well it deals with being left running…
hopefully I’ll never see memory usage of 1,268,300k ever again.

I’ll update with more as I remember things.

Update:
I upgraded to ff3 on my macbook.
- Colorzilla needed to be upgraded ColorZilla v2.
- Bookmarks transferred just fine…
