I got this same error every time I attempted to open FF: --------------- ben@ben-desktop:~$ firefox -safe-mode
(gecko:13540): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'Times 12' Segmentation fault (core dumped) ---------------
Removing the Times Truetype font I had installed fixed the problem, and now Firefox starts, though obviously this is not the ideal solution.
