Luakit – fast, extensible, and customizable web browser

While switching to the WebKit 2 API means a vastly improved security situation, not all distributions of Linux package the most up-to-date version of WebKitGTK+, and several package very outdated versions that have many known vulnerabilities. As of November 2017, Arch, Fedora, Gentoo, and Ubuntu all have the latest version of WebKitGTK+, but Debian and OpenSUSE ship outdated and vulnerable versions in their stable channel. If you use Luakit for browsing, it is your responsibility to ensure that your distribution packages an up-to-date version of WebKitGTK+!
