Since I upgraded to Ubuntu 12.04, every time I try to open a PDF through Firefox (which I like to do quite often as I read a lot of PDF documents and downloading each then deleting is tiresome) I get the error message:
Could not launch Adobe Reader 9.5.1. Please make sure it exists in PATH variable in the environment. If the problem persists, please reinstall the application.
If I launch Firefox from the terminal the message it gives when attempting to open a PDF is:
(firefox:5989): Gtk-CRITICAL **: IA__gtk_widget_realize: assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed (firefox:5989): Gdk-CRITICAL **: IA__gdk_window_set_back_pixmap: assertion `GDK_IS_WINDOW (window)' failed /usr/bin/acroread: 23: exec: /opt/Adobe/Reader9/Reader/intellinux/bin/acroread: Permission denied
How can I fix this?
I should mention loading a PDF from say the Desktop is fine. I only get error when loading a PDF via the browser.
