Does anyone else find that they can't ever tell a difference in browser speed in day to day use?
I switched to FireFox for my personal use a few years before the "Quanutm" update when it was theoretically much worse than Chrome and didn't notice a difference. For the last few years, I've been using Chrome and FireFox side by side with Chrome for work and FireFox for my own stuff and switching back and forth feels pretty seamless. (With the exception of Gmail which is abysmal on FireFox, but I somehow doubt that's Mozilla's fault)
Chrome feels a little faster to me, but I stick with Firefox because it doesn’t give me the same creepy big brother feeling as chrome and I can spare a few milliseconds per page load.
Come to think of it, I primarily use chrome to double check UI changes on a page served from my local computer. That’s probably the main reason it feels faster.
