After a system upgrade, firefox on a remote machine (connected to via SSH, not upgraded) does not open a browser-window, anymore. Launching thunderbird gives the same result, other applications (e.g. Emacs, Xterm, all remote) do work as usual. I use Xfce4. I tried to find any messages in logfiles or with strace that help me to solve this problem, but had no luck -- I have too few knowledge about the technologies involved. Please let me know, what other information I should provide. # emerge --info Portage 2.2.28 (python 3.4.3-final-0, default/linux/amd64/13.0/desktop, gcc-5.3.0, glibc-2.22-r3, 4.4.0 x86_64)

Some more information: * I also cannot start firefox in the other direction, switching SSH client and server (both machines have desktop environment, they don't share home directories). * I installed firefox-bin-44.0.2 on another machine (a server that is not used for desktop applications) and can launch it in an SSH session -- everything fine. * Using that firefox-44.0.2 on the problematic machine (via binary package) results in no browser-window.

I would advise troubleshooting in IRC, on forums or on the ML. Bugzilla isn't a good place to get tech support. Feel free to re-open the bug after troubleshooting fails (indicating there is a bug, rather than a quirk with your system config).
