Firefox is now objectively better than Chrome in every way. I would recommend switching moral reasons aside. Chrome's memory management is abysmal. I now get the same shudder when I see someone with chrome on their machine that I used to get when I saw someone running Internet Explorer (which may even be better than chrome now too).
i'll tell you though, the #1 subjective thing i hate is that single-click in the Chrome (Chromium) omnibar doesn't honor OS selection convention. unless you're on windows, where single click selects-all. having this behavior forced on Mac is jarring and awful and no amount of pleading would convince the dictatorial "my way is the right way" attitude of the gatekeepers. they refuse to even have a hidden flag to control this behavior. it's actively hostile.
the incongruity can be seen by clicking in any form field. eg chrome://flags search field. Note that single-click merely places the cursor on mac in a form field. then go to the omnibar. single-click selects-all. ARGH!
I had hoped Edge would fix this, but alas, no. (Also Opera keeps this behavior.)
Fast forward to newer behavior of hiding the protocol from the omnibar, until you click on it. Now when you click (or click-drag, the "proper" way to select less than the entire URL in one stroke, thank you oh overlords), as soon as you release the text changes and your mouse is no longer at the selection point. ARGH!! so awful.
I can't tell you how much I hate this poor implementation choice. However it's not enough to push me to FireFox, which is subjectively very much worse than Chrome.
