Source: firefox Version: 58.0~b4-1 I am working on a goal to have Debian GNOME not ship gtk2 by default for Buster. (There's some other desktops that might be able to achieve this too.) The only significant blocker to this in my analysis is Firefox.
Firefox has only one file that naturally depends on gtk2 which I believe is only used by the Flash plugin now: /usr/lib/firefox/gtk2/libmozgtk.so All the Flash plugin packages in Ubuntu and Debian already depend on libgtk2.0-0 - adobe-flashplugin (Ubuntu only) - flashplugin-installer (from source flashplugin-nonfree ) - pepperflashplugin-nonfree (works in Chromium not Firefox but mentioned for completeness) Therefore, I propose we use the same workaround we've used in several other packages to drop the depends on gtk2. This has been accepted for Ubuntu's Firefox 58. See https://anonscm.debian.org/git/pkg-gnome/gnome-themes-standard.git/commit/?id=4c5691e The only risk I see is that it is possible for someone to manually try to install Flash without using the system packages but I don't think we should worry about that use case. I am aware of https://bugzilla.mozilla.org/1377445 but this issue is about the binary dependency, not the build depenedency. By the way, chromium-browser in Debian now depends on gtk3 but not gtk2. Thanks, Jeremy Bicha
