IE 6.
Browser extensions
NoScript generally disables scripting on sites. Some Dreamwidth functions depend on Javascript. To get these functions to work while using NoScript, either temporarily or permanently allow Javascript from dreamwidth.org.
One report of Post an Entry page (http://www.dreamwidth.org/update) being affected by GetGlue extension for Firefox. User picture will not update in preview (selected image will show up in post), switching between RTE and HTML editor does not work (does not appear to process javascript). Disabling or removing plugin resolves issues.
