[twitter-dev] Permission denied error in Firefox when trying to add a tweet-box with @anywher

I'm just trying add a twitter's tweet box with @anywhere but I'm getting the following error in Firefox: Permission denied to get property Window.jQuery from https://api.twitter.com; It works fine for me in Chrome. All I have on the page is the code snippet from Twitter's api tutorial which is:

[twitter-dev] anchor to twitter.com/home?status authentication conerns

If I provide an anchor that that takes the user to http://twitter.com/home?status=TheirStatusMsg, I don't have to worry about oAuth or any authentication issues, right?
