I have the Dell Mini 9 with Ubuntu. After an auto-update a few weeks ago, whenever I try to launch Firefox I get the message:
Failed to execute child process No such file or directory
So I tried uninstalling it in the Add/remove applications menu, then I told the command line
sudo apt-get install firefox
but it responds by telling me that Firefox is already the newest version. So I try installing it again in the add/remove menu, and it claims that the operation is a success... except it still doesn't work after that.
Is there a more thorough way of deleting the program? I'm not too experienced with Ubuntu and unsure how to proceed.
