Well, last time I checked (which was before the recent layoffs) Mozilla Corp had around 1,000 employees, most of whom were working either on technology or around technology (i.e. I'm including designers, support, end-user research, managers) and a revenue of ~800 M$. I'd be really surprised if the budget per employee (including salary and employer taxes) was below 300 k$ per annum.
That's already close to half of the revenue. I won't try to guesstimate operating costs, but Mozilla needs to rent plenty of cloud computing power for both CI (heck, Mozilla pretty much invented Continuous Integration), Telemetry, Sync, Accounts, MDN, ... Offices in Silicon Valley and around the world (several of which have closed in recent years) can't be cheap, either.
I also seem to remember that Mozilla had marketing campaigns that cost dozens of millions of dollars. Pretty cheap in comparison to what e.g. Google can afford, but less so for a smaller company.
I realize that there's lots of guesses here, but I believe that my earlier claim makes definite sense.
