This goes back to what I said about using pointers as implementation details. If you put unique_ptrs in to a _global_ then you're doing something stupid already. Just think about it. Why does something that can only be pointed to from one place need to visible globally in the first place?
My point is all Rust does is force you stop and think, and while C++ lets you do dumb shit, it's hardly fair to blame the language when almost-safe C++ is actually cleaner and easier to read and write than dumb C++.
Build your own handle types with well-defined ownership semantics, use explicit move() sparingly, pass objects by value, use references, utilize the stack and temporaries. Only put pointers inside the guts of classes and your data structure implementations. These techniques go quite far.
And Firefox as an appeal to authority is hardly compelling. As another, I've seen bug fixes in Chromium where the original code quality is so poor it was hard to believe it came out of Google. Of course, since then i've learned most C++ out of Google is total crap.
