Developing a rendering engine that can handle css, html, javascript, while also rendering a website in the exact same way as Chrome and Firefox is a huge tasks, and not something a hobby programmer can whack out in a few weeks. Thats the reason why even Microsoft abandoned their own rendering engine, because things did always look and work different in IE.
oh good firefox. Wonder what other browser i can use, oh wait…
Can someone just make a minimalist browser that isn’t chrome/firefox based?
