Which company is my Firefly rental contract with?

Firefly is a trademark of Hertz System, Inc.; local stations are run by licensees or franchise partners, so the contracting company is the one named on your rental agreement. The company named on your rental agreement is the one you contracted with; it can differ by country and for franchised stations.

What must Firefly prove before charging me for damage?

that the damage exists: dated photos taken at return; that it was not there at pickup: the pickup condition report and photos; that it was found at return, ideally in an inspection you could attend; what it actually cost: a repair invoice or an itemised quote; the contract clause relied on, within the excess or deposit you agreed. In Spain, Portugal, Italy, Greece, Croatia and Malta the general rule is that the party claiming payment proves the facts. Pre-written clauses that shift that burden onto the consumer may be unfair (Directive 93/13/EEC).
