If you don't want to be tied down to a desktop, you need direct access to your computer in the cloud. Since Firefox runs just about everywhere, it's a good place to start to set up a reliable way to access your accounts. Blog & Social Delicious Bookmarks is the recommended and official Firefox add-on for Delicious, the world's leading social bookmarking service (formerly del.icio.us). It integrates your bookmarks and tags with Firefox and keeps them in sync for easy, convenient access. Syncing slows down startup, though. ScribeFire Blog Editor is a blog editor that integrates with your browser and lets you easily post to your blog. They've also integrated their affiliate Quick Ads advertising program, which I haven't tried.
