Each to their own. I would never trust the judgement of the most important piece of software on my computer to a small group of tinkerers maintaining a fork of someone else's massively complicated and deeply outdated source code. I don't care who they are—if they don't have a big enough reputation on the line, there's no reason to trust them. I'm sure your cousin is super trustworthy, but that doesn't mean anyone should put him in charge of the armoured vehicles division of a bank. Besides, it's a lot easier for a microscopically small and individualistic outfit like Pale Moon to never disappoint you compared to a large, managed entity like Mozilla which has disclosure policies and hundreds of employees each with their own priorities and agenda.
