I recently upgraded Firefox on my Mac laptop (running Mavericks) to version 39. Now I find that version 39 won't work with my company financials. They have advised downgrading to a previous version. How do I downgrade? Thanks.

In what way doesn't it work? Could you be more specific without disclosing anything too confidential?
