Using GTK+ 2.x and GTK+ 3 in the same process is not supported . . .
I had been using firefox just fine, until I started to get the error message:
$ ./firefox -safe-mode & [3] 4499
$ (firefox:4499): Gtk-WARNING **: GTK+ module libgail.so cannot be loaded. GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported. close failed in file object destructor: sys.excepthook is missing lost sys.stderr
[3]+ Exit 1 ./firefox -safe-mode $
How should I troubleshoot such error?

It is likely that you have an old version of libgail.so that is part of GTK+ 2. You will have to check your software update to see if you can install a GTK+ 3 version.
