Isn't there one that starts with a V that is non chromium? I can't stand Firefox and being chromium is like being Linux it doesn't mean that all Chromium browsers are the same.
And, realistically, it's either one of the Chromium-based browsers or Firefox-based browsers under Windows.
You can install the ancient and unsupported version of Safari under Windows, but that's of very limited utility in my opinion.
I am glad to see that Mozilla Firefox has remained a power player in the web browser space. As someone who works with screen readers and accessibility issues, you often need to jump to/from Firefox to/from a Chromium-based browser whenever some web page, for some unknown reason, simply doesn't play well with one of the other. Were only Chromium-based options to exist, many dead ends that needn't be so would exist.
