Bug 1684365 - Add a null pointer check so that Firefox won't crash when it can't initialize mRemoteServer r=stransky Firefox 84.0.1 crashes under Gentoo Linux if it is started in Wayland mode and if it was compiled WITH Wayland support and WITHOUT dbus support. I traced down the problem to line 172 of toolkit/components/remote/nsRemoteService.cpp: nsresult rv = mRemoteServer->Startup(mProgram.get(), mProfile.get()); mRemoteServer is NULL and Firefox crashes. This patch adds a NULL pointer check before that line.
