As a blog writer, I’ve been using a few that smooth out the experience and get rid of a few annoyances.
Here are a few suggestions.
Windows Live Writer – Use Writer, you can easily log in all services to share photos and video – Windows Live, WordPress, Blogger, LiveJournal, TypePad, etc..
WriteToMyBlog – WriteToMyBlog is a free web based word processor for your Blog. Create Post Entries for your Blog from right here, completely free, no membership required, can Post to multiple Blogs simultaneously, manage your Posts, works with all major Blog programs, and is easy-peasy!
Scribefire – Performancing.com’s popular split-browser blog editor. Multiple blog management, categories and simple source editing. FTP Uploads are available but buggy. No good image support.
Deepest Sender – Very similar to ScribeFire, these two extensions lack greater features like image uploading, time-stamp editing and compatible tagging. Both are very easy to set up.
Resizable Text Area – If you stick with your regular blog editor, such as Wordpress, this extension comes in handy to resize the text area quickly and freely.
Spellbound & Google Toolbar - Inline spell-check, ala Microsoft Word. Use the extension or Google Toolbar’s built-in spell-checker. Both work great. Superseded by Firefox 2’s built in spell check.
Tabinta – turns the Tab Button to a text editor spacing tab rather than cycling through the web forms. Only interacts with the text area, otherwise does the regular Firefox tabbing.
Split Browser – Great when copy and pasting content and URLs, this extension makes it easy to split any tab any which way. Put your editor in a ’sidebar’ and continue surfing the other tabs in the other pane.
Copy Plain Text – This is a can’t-live-without extension for me. When I copy text, I don’t want any of the original site’s formating, links or text-link-ads to be copied over as well. Just the text. That’s what this extension does.
Copy As HTML Link - Use this extension in conjunction with Copy Plain Text to create links for your posts. Only make links when you want with the text you want.
