Yes, I've tried to replicate Chrome's UI with Firefox extension. But it feels like I'm using extensions. Furthermore, I really don't enjoy configuring browsers because between work, school, and hobbies I use a lot of different machine. For this reason, if I'm using firefox, it's usually with the default UI... which is not my personal preference.

Take a cursory glance at each of the two stores:
https://addons.mozilla.org/en-US/firefox/
vs
https://chrome.google.com/webstore/category/extensions
Aesthetically speaking, the firefox add ons page is the Tux Racer to chrome's Mario Kart.
One has the passion and enthusiasm of well respected open source volunteers behind it, and the other has a sleek high quality shine only our dear corporate overlords could deliver.
This is minor, but it sets the mood the for the whole experience of add ons.
(Of which, I only need uBlock Origin"). In general, it's easier to find what I'm looking for, see what's trending, and generally browse for extensions in the chrome store.
EDIT: The chrome store is also much faster and more responsive.
Aside from that, Chrome seems to have more active developers because of it's better brand name. On /r/cscareerqustions, for example, you'll hear people ask about ideas for resume-boosting side projects. One of the first answers is usually "make a chrome extension". I have yet to see anyone say "make a firefox extension" or "make a cross platform browser extension".
Either way, it's all personal preference. I'm sure you prefer a different model car, style of clothing, and a favorite color than me too. It's all ok. There's no right answer here.
