Edit: Changed 'disabled' to 'removed' in the first sentence, as it's probably clearer.

Mozilla aims to ship a default configuration that works well for a large number of users. Of course there'll be people -- like yourself, apparently -- who'd prefer some things to be configured differently, but what you'd like changed is entirely up to you.
Maybe you should be grateful Firefox offers (quite a lot of) customisation opportunities, instead of just posting snarky remarks.
Are you sure they're trying to ship what works best for most people? I've not read that anywhere. If they really wanted people to have a choice, they wouldn't be adding configurations that can't be switched on/off through they're preferences menu - like for example, that crazy bar they just added a couple of releases ago - oh.. and which apparently you are not allowed to switch off no more, not even through about:config, according to sibling comment. Also, they have a track record of breaking old configuration options quite often through updates.
I am grateful by what they offer - just not sure they're not sneakily changing course, similar to what chrome did.
That's called user feedback. Users are always right. And looking at Firefox's browser share they are not getting too many new users anymore. Making the life of your existing users a little more miserable does not sound like a very sustainable strategy.
Not in any useful sense. "What do I need to turn off this time" presumably just implies "they should never change anything, the product is perfect already". (Which one was the perfect version, out of curiosity?)
You're exaggerating. The problem isn't that Mozilla changes things, it's that they've set the bar too low for changes. Many of their updates seemingly deliver change for the sake of change, when a more reasonable strategy would be to require a change to be compelling enough to outweigh the frustration and friction it will cause. An imperfect UI that users know how to use is better than a moving target UI that constantly brings new surprises.
