I think this has more to do with the machine, rather than the browser.

The link broke my IE in the same way..  Machine slows, and locks,
requiring a forced hard reboot.

Laptop with 450mhx cpu and 128 meg of ram, with a 5 gig HD
Running Win2k, with IE6 and Firefox 0.9.2

However, my collegue's machine (1.6 ghz cpu, 1 gig ram) worked fine in
both IE and Firefox, although firefox did render the page FAR more
slowly than IE.

There may be an issue in how firefox handles .BMP files, but I'd be more
concerned with cpu and mem usage on older machines irrespective of
browser.
