If, like me, you installed the Microsoft Silverlight plugin and found that it ate all your bookmarks and crippled Firefox, hopefully what I just did will also work for you: uninstall Silverlight and reinstall Firefox. And stop trusting Microsoft.
Speaking of the new computer, I will say that I'm not completely hating Vista, but I'm not loving it, either. It's certainly pretty, but its kruftiness has more or less erased the performance gains I expected to gain from a faster processor and larger hard disk. I'm seriously considering running Ubuntu from CD and seeing how I like it. Anybody out there who's tried it and has advice?
