I cannot post even a medium sized image to facebook.com (and other sites) using Firefox (12).

I can post a 16KB image file to facebook.com (and other sites) successfully using Firefox, Safari, and Chrome.

Why is Firefox failing to successfully upload even medium sized images?

This shows that Safari is successful where Firefox fails with 6.2MB image upload

This shows that Firefox IS successful when uploading a very small image (16KB)

As already made clear in this post, this error message is uniquely correlated with Firefox.
