Urs' blog prompted me to download Firefox for browsing online. I'd been meaning to for a while and find little different from my experiences with Navigator or Safari. Internet Explorer, I abandoned long ago.
The little differences like learning keyboard shortcuts for switching between tabs has been smooth. Importing our bookmarks from Safari was quick and painless. And Blogger has more options available to me so I don't have to rely on my very limited Html knowledge.
The orientation continues and my assessment is a work in progress.
