I'm apparently one of those rare people who never switched off Firefox - it's been my default browser on Mac and Linux for years. Open source, good plugin ecosystem, and does everything I need (not a web developer, so the dev tools were never a strong selling point for me).
I've used Chrome here and there through the years, but the more invasive Google became about data collection, the less inclined I've been to use their tools. The latest moves to block ad blockers, coupled with nearly every other browser using their engine, had only reinforced my decision to stay with Firefox.
Diversity makes for a healthier ecosystem.
I'm the same way. I tried Chrome when it was new but at the time it didn't have a NoScript equivalent so I went back to FF.
Chrome has had NoScript equivalents for a while, you should try it again!
I suspect for most people who hadn't switched already, that ship has already sailed.
Chrome had something of an edge over Firefox for a while with a more responsive UI, but since Firefox Quantum it hasn't really had anything besides some creepy Google integrations.
Edit: Chromium is also easier to embed, but that doesn't really matter for the purposes of chosing a browser.
Its strange, for me. I remember getting super pumped about Chromium when it went live in '09. Then, somewhere along the line, I felt like a boiled frog.
Honestly, a big change for me was symbolically realized by The logo change: https://en.wikipedia.org/wiki/Google_Chrome#/media/File:Chro...
It went from this space-age, nerdy little project to a cleaned up design that signified its shift to a position as a core Google product.
Does Chromium have the same privacy issues as Chrome does?
For me, Google's hold also manifested as complete absence of support for H.264 on Mac, because calling the Cisco's freely available openh264 is ‘too slow.’ In Linux, distro maintainers patch in the support for openh264.
