"Remember how you asked me to clean your computer from these toolbars and make it faster? This problem may happen again if you browse the web without uBlock Origin installed. Chrome doesn't support it now, so you have to use Firefox. Ignore websites pleading you to switch back to Chrome. Some of them will try to sneak in this toolbar garbage to you. Actually, stop visiting such websites because they're staffed with assholes who want to abuse you. But if you must, do it in Firefox. Yes, preferably in Private Browsing."
As others said, regular people follow the tech crowd. My family uses Chrome because that's what I've been telling them to install and/or installing for them for the past few years. But the very first thing I also install for them is uBO, and if that stops working, Chrome goes out of the window.
The main reason Chrome is so popular is because tech people have been saying "just use chrome" for forever.
Firefox is taking back that role. It'll take time, but with google becoming such a PII hoarder, it's a change that will likely continue.
Utter bullshit.
Chrome is dominant due to two factors:
a) Distribution deals by Google to bundle Chrome everywhere they can. (Including shady crap like 'warez' sites, illegal music, OEMs, etc.)
b) Google aggressively peddling Chrome on their properties and making them deliberately slow and buggy with other browsers.
It's not a coincidence that Gmail suddenly became slow and buggy under Firefox with their latest redesign.
