While browsing via Iceweasel, and trying to book tickets for upcoming Tori Amos show, I was surprised to found java web form, that was *not* working in Iceweasel or microB, while works perfectly in desktop Firefox. It was first time I was not able to use web form via my N900 and had to use desktop.

While trying to access page, I got this error: (see attachments)

Any clues?
