While I love Firefox and all the features it has which Chrome doesn't, I do prefer the Chrome interface aesthetic.
You can install MaterialFox, which changes the Firefox interface (not the positions of things, just the 'skin') to look 90% like Chrome.
You can install it from here: https://github.com/muckSponge/MaterialFox
Basically, you just download and copy the files into a folder called "chrome" within your Firefox profile. They have more detailed instructions on GitHub.
