For several years now it has seemed like every notable change in Firefox has been about removing a reason to use Firefox instead of Chrome. (There are certainly reasons for the opposite case, including but not limited to the fact that every single website is certainly tested to work in Chrome.)
Now, I've been using Firefox as my primary browser since before it was called Firefox, and I'm quite used to it and unlikely to switch to anything else, but boy are they (at the Mozilla Foundation) trying hard to make me.
