As I mentioned in the prior thread, I primarily use Firefox. Mostly because I use Macs, Windows PCs and Linux PCs and it provides me the same interface, with the same skins and plugins on all three platforms.
I occasionally use Safari and Edge, but usually only if Firefox doesn’t work on a page. Safari because it’s an Apple standard. Edge because it’s also cross-platform, is based on Chromium, and is not from Google.
I suppose I should consider dropping Edge and instead get Chromium project builds, so I can get the engine without any corporate customizations. But I use it so rarely I don’t think it will matter much.
