Firefox usage is down despite Mozilla's top exec pay going up
There's a quote from the CEO saying that they looked at the market and felt like they were being underpaid.And they can't reduce their salary now because it'd be unfair on their families.Firefox has a problem. It gets most of its revenue from Google. 
They need a different revenue stream but their ideas haven't worked.Their executives are clearly failures. 
But with such high pay, they're cashing out. Buying themselves mansions etc.Isn't that pretty much admitting that they're on a sinking ship?
