If you're interested in genealogy, I recommend
Reunion from LeisterPro.
I've been using it since version 1. Don't know how long that's been, but it came on a floppy disk. 🙂 I would imagine it could import a wide variety of databases.
By the way Safari wins the speed test right now. Of course Firefox is darn good too; I like its ability to save and restore a browsing session.
Between the two, using the most recent versions, only Safari passes the
Acid3 test. To my knowledge, Chrome and Opera are the only other browsers that do.
No version of Windows Explorer does.
For what it's worth. 🙂
