alt Hacker News> And I can't test the new version of Safari on my Windows or Linux devices because Safari isn't available for them.
You can download three Linux-compatible WebKit-based browsers from Apple's WebKit page:
Epiphany Technology Preview: https://webkitgtk.org/epiphany-tech-preview
WPE: http://wpewebkit.org/download
WebKitGTK: http://webkitgtk.org/download
There are subtle differences. From the top of my head, differences with osx include the font rendering and the tab order (which is broken for everything except form elements).
