After updating firefox on Centos 6.4 it started showing the following error and would not start firefox.
The issue was resolved after installing
Still if you get the following error:
Then update gtk and libX11, in my case gtk was already updated to the latest version so, just updated the libX11 and it worked
$ firefox\n /usr/lib64/firefox/firefox: symbol lookup error: /usr/lib64/firefox/libxul.so: undefined symbol: gdk_window_get_visual
The issue was resolved after installing
$ sudo yum list gdk-pixbuf2
Still if you get the following error:
/usr/lib64/firefox/firefox: symbol lookup error: /usr/lib64/libgdk-x11-2.0.so.0: undefined symbol: _XGetRequest
Then update gtk and libX11, in my case gtk was already updated to the latest version so, just updated the libX11 and it worked
