I don't think your last sentence is a particularly generous summation. :)
Maybe I'm an anomaly in the HN crowd, but I never really got into extensions even when I was using Firefox or Chrome as a daily driver. I have an extension for 1Password, an extension for a read-it-later service (for years Instapaper, lately GoodLinks), and somewhat grudgingly, an ad blocker. And sometimes a user style sheet extension. I've tried other extensions at various points and they've never really stuck, not even the "vertical tab" style extensions that I want to love but always find ugly and distracting. (OmniWeb, RIP, is the only browser I ever used that had what I thought was a great implementation of this.)
And I use Chrome daily at work now, because there are a few internal sites that require it (and one that inexplicably requires IE 10, which Chrome turns out to be better at faking than Safari), and... it's fine? But it feels just a little slower, it's harder on the battery, and there's very little about it that I miss when I'm back in Safari on my personal Mac. Maybe if I was deep into web development again, this would change, since Safari's dev tools always seem to be a few steps behind Chrome's. Maybe there's some magic can't-live-without extension I could find on Chrome or Firefox that would sway me to stick with one for the long haul. But for years, I've enjoyed the web, and I've enjoyed it on Safari. [shrug emoji]
