IE connection settings

I have long used FF at home, and so thought that portable FF would be the perfect thing for use at work!!

unfortunately I am not sure how the computers here are connected to the internet (we have many servers etc) and the only people who know are the IT helpdesk people (who would never help with FF)

autodetect settings gives no joy, and i remember having to call the helpdesk to have my computer connection settings changed when i started working.

is there any way for firefox to use the IE connection settings or for me to be able to see them, as they are hidden in the internet explorer options.

Cheers all!!!

oh, and i have v1.5
