I remember when Chrome was released, all marketing was on how much faster it rendered webpages, I never saw that as an issue, Firefox was fast enough, I tried Chrome for a bit, and hated the UI, I remember being confused as to why everyone loved Chrome suddenly, and frankly, I still am a bit confused by both the sudden shift, and the absolute market dominance by Chrome...
I switched from FFX to Chrome back in the day because Chrome tabs were all independent processes in task manager, and one crappy website wouldn't kill my whole browser.
When Google started their war on addons, I switched back to Firefox.
I hated Chrome's UI so much that I switched from Firefox to Pale Moon when Firefox started the whole Australis design language, and only switched back when the current design was launched
I grew up with a 56k modem. Anything after adsl is warp speed for me. I never understood or observed the speed differences between browsers.
Maybe I'm just so slow myself that I dont notice the difference but come on.. how much can it be? A few seconds? Who is so busy that a few seconds is a worthy amount of time to try and save (not talking about F1 drivers here)?
