Using the Canon ScanFront 220/220P with Firefox

We've gotten a new document scanner for bawue.net in order to better handle our documents and our snail-mail communication.
The Canon ScanFront 220P is a network scanner which does (among other things) optical character recognition and is able to send the resulting document as a PDF via e-Mail or upload it to a FTP Server or a SMB Network share.

The device itself is running Windows CE in order to accomplish all that which is fine as it therefore needs no computer connected to it as some other scanners do.

A real problem for the Linux user howerver is that Canon seems to have handed the development of the scanner's web interface to some clueless and moronic developers.
There's simply no excuse for designing a web interface which only works with Internet Explorer and doesn't even allow a Firefox user to log into the interface.
I'd expect MUCH better from a global company such as Canon, especially when the scanner in question costs about US$ 2,150.00

If the device would have been running Linux and the sources would have been delivered as requested by the GPL I'd have a working scanner here and Canon's development team would have had a nice unified diff in the mail fixing their problems. That way, all they are getting is an acrid mail.
Another reason to favour open source operating systems for any development work. Some companies seem to clearly get this.

In the meantime tough I need a working scanner. Greasemonkey to the rescue: I've written a small GPL3 licensed Greasemonkey User script fixing the problems in the ScanFront webinterface. Naturally, one has to have greasemonkey installed to use this script.

It currently fixes the login prompt, makes the "New User" button work, fixes an onload-recursion in the address book and makes the job-control window work when selecting the destination address for a scanjob.
Most of these problems stem from the fact that the Internet Explorer XML parser seems to be somewhat sloppy and does not make a difference by getElementById and getElementsByName.
My userscript works around these issues but a real fix can only be delivered by Canon.
