Modern users spend lots of computing time using their web browser. Many web browsers work on Debian GNU/Hurd: Emacs' eww, lynx, Surf, Luakit, Netsurf, and Dillo. However, users must compile netsurf and dillo from source due to PATH_MAX issues. While luakit should work for most users' needs, the Hurd does lack a modern web browser such as Chromium, Firefox, Brave, or LadyBird.

Some years ago, Debian GNU/Hurd did support an older version of Firefox. More recently, Sergey did manage to port and run and older version of LadyBird. A talented and dedicated GNU Hurd developer could port a modern web browser, but it would take a significant amount of work. It may take a continuous herculean effort to keep the port up to date.
