Internet Explorer, for all its flaws, makes it pretty easy to save all your bookmarks at once (export). You can later import them (you can also import them with FireFox).
Safari for Mac? I can’t find a feature on any menu that allows you to save all your bookmarks to one file. I can’t find anything that allows me to upload my saved IE bookmarks pages.
I’m thinking there’s no way that Apple could have left this feature off, but they’ve been known to do stupid things before (Auto fill that you just_can’t_turn_off).
Thanks for the advice thus far, but I was hoping for a deeper summary of why Safari has these deficiencies and what people think about them. Any further thoughts available?
