Version: 49.0~b1-1<br>
Severity: important<br>
<br>
Hello,<br>
<br>
After upgrading firefox from 48.0-1 to 49.0~b1-1  it segfaults at startup<br>
when $DISPLAY is not "owned" by the user running firefox. This shows up<br>
e.g. when running through ssh adifferentuser@localhost or with su - and<br>
manual setting of DISPLAY and XAUTHORITY.<br>
<br>
At the time of crash a "Firefox Update" window is open. (See attached<br>
screenshot).<br>
<br>
gdb backtrace (with MOZILLA_DISABLE_PLUGINS=1) attached.<br>
