We're Here To Serve - sort of

I'm in the midst of a job hunting campaign. I went onto a job site that I haven't used before.

Almost immediately after I arrived on the site I was informed that I had an unsupported browser (Firefox - 3.5.5).

These folks are supposed to be on top of the IT Industry but their system only supports Internet Explorer.

As of the end of October 2009 Firefox had a 48% adoption rate versus 38% for IE 6.0 - 8.0.

Not sure why I have to accommodate their system. Shouldn't they be keeping up to date?
