The Twitter embedded timeline widget isn’t displayed on my site when viewing from Firefox 3.5.
I get the following error in the browser console:
uncaught exception: [Exception… “Not enough arguments” nsresult: “0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)” location: “JS frame :: http://platform.twitter.com/widgets.js :: z :: line 28” data: no]
