I just installed ScribeFire, a Firefox plugin that lets you blog directly from your browser. So far I am really impressed! I often find it hard to motivate myself to post an entry because it’s a process to go to my blog and open a new post. Then I have to remember to finish the entry and it probably gets lost in a tab somewhere. ScribeFire can split your browser window and you can post while you browse. This means no flipping through tabs!
One thing I just noticed, however, is that they don’t do a very good job of integrating with WordPress’s image uploading. It’s not easy to have thumbnails automatically created 
ScribeFire.com has a list of additional features:
- Categorize and tag your blog posts
- Upload images
- Set timestamps
- Save works-in-progress as notes
- Post an entry as a draft
- Share your posts on social websites
- Upload files via FTP
I’m going to use this for a while and see how I like it. Let me know if you’ve had good or bad experiences with it.
