It's getting there. They recently added multiprocess support. A new CSS engine is coming. In the further future we're going to get more and more pieces of their new rendering engine in.
Personally, I dropped Chrome 2 years ago or so, for the same reasons (moving away from everything Google that I reasonably can). Firefox is more painful to use, for sure, but it's gotten "okay" enough that I'm willing to keep using it in favor of its benefits (privacy).
By the way: In Firefox, open `about:support` and check that "Multiprocess Windows" says something like "2/2 (enabled by Default", where the numbers can really be anything but 0. If it's disabled, that means your Firefox isn't using the new multiprocess support, most likely because you're running an incompatible addon.
