@gugurumbe I think you're mixing up the rendering engine, of which there are really only 2 or 3, and the browser, which is the full application around that engine. Wikipedia lists 9 major browsers for 2024: https://en.wikipedia.org/wiki/List_of_web_browsers
The fact that browsers are extensible with plugins makes this level of choice even broader. There are 150K+ Chrome-compatible extensions and about 35K+ Firefox-compatible add-ons. That's a lot of opportunity to vary the browser experience.
