I keep getting the Failed to Execute Default File Manager for when I try to open files from Firefox. The other error I get is I can't use any shortcuts to get to folders from the panels. I only can use the desktop to get to any folder. Any ideas on how to fix this? I figured I could reset the File Manager. Can this be done? if so, how?

Run this command: exo-preferred-applications and go to Utilities tab and in File Manager selection list chose your preferred file manager. You would get Nautilus if it is installed in your system. Chose that if you want to set it as default and close. Reply what happens.. –  Saurav Kumar Oct 9 '13 at 16:52
@SauravKumar Okay, since I'm running on Xubuntu, I have Thunar installed but no Nautilus. I did what Mitch said to do below and than what you just posted here (Dropbox started working) sta and made Nautilus my default file manager. Everything works now. It seems there probably something wrong with Thunar (the default file manager for Xubuntu). Thanks for the help though. Wish I could give you credit too but I don't have enough reputation points. –  user2784630 Oct 11 '13 at 15:47

Try this. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo apt-get --reinstall install nautilus

Thanks, was using Thunar since I have Xubuntu installed. This installed Nautilus for the first time, made it my default file manager and everything works now. –  user2784630 Oct 11 '13 at 15:51
