Firefox Extensions

Unofficial Addon Toolbar by StrangeJ + Thlayli
This extension adds a toolbar to Firefox which makes using SU an easier and better experience. The following scripts are included in the toolbar: Choose Archives, Random Archives, Backup Blog, Advanced PhotoBlog, & SU2Bookmarks. You can also use the toolbar to change your content filter settings with a single click, navigate blogs with the built-in Latest, Prev, Next & First buttons, or quickly visit any stumbler's blog by entering their name in the toolbar. It even stores the names so you can quickly visit friends.

wySUwyg by induscrypt
This extension integrates a Xinha WYSIWYG (what you see is what you get) editor with SU. Although it's currently in beta it already has many great features: All the color themes available on SU are preloaded in wySUwyg so you can select the theme which matches the current page. The content width is (almost) the same as that of SU so lines wrapping can be previewed. Resizing images will always produce SU-friendly code. In fact, everything that's available on the toolbar is completely compatible with SU's posting format.
