Tor and MITM SSL [duplicate]

In my company they have MITM/SSL in following way. There is a proxy to whom all PCs connect. Now the company installed some trusted certificate authority (e.g. ISSUER-COMPANY-NAME) on our computers. When I go to facebook it shows me that it has certificate signed by the issuer that was installed by our company. I am curious will Tor hide my traffic in such setting? will they see say my facebook password if I use Tor?
