Netsurf is great for platforms with limited resources, but hardly suitable for modern browsing needs. For example the JavaScript support is still in its infancy, it has no support for HTML5 video, etc. On NG it would be a huge step backwards even compared the outdated Odyssey 1.23.
I think utri was suggesting some people could help to implement/improve these features.
They are being dealt with, but it's a small team so progress is slow. Patches are usually welcomed!
