Are you running the official Linux build from Mozilla? If yes, is it reproducible with a fresh profile? https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
Just tested with the official build with a fresh profile, was reproducible. Here is the crash report: https://crash-stats.mozilla.com/report/index/19ed74b8-9615-436b-9647-e98ca2160611
Since FF46, Gtk3 is supported. Could it be related to that? Are you using a theme?
Might have something to do with the window manager. The crash happens on xmonad 0.12 but not on i3 4.12.
This has been verified by a user on #firefox on freenode, he also run xmonad, we've verified it with: http://ftp.mozilla.org/pub/firefox/releases/48.0/linux-x86_64/en-US/firefox-48.0.tar.bz2 and ran it with: mkdir /tmp/test-profile ; ./firefox/firefox -no-remote -profile /tmp/test-profile and crash report: bp-e0a649af-8919-485a-bae3-64f772160810 I can't reproduce it on mate, gnome-shell so xmonad sounds like a hard dependency.
Reproduced on bspwm window manager. https://crash-stats.mozilla.com/report/index/ac2519d3-e399-4f23-9619-965f02160810
