I upgraded from 11.10 to 12.04, now when I try to run Firefox from the icon it pops up this: "Missing Profile. Your Firefox profile cannot be loaded. It may be missed or inaccessible." I already tried to remove Firefox and re-installing it. And the command
sudo chown -R $USER:$USER ~/.mozilla
I've also tried to delete the profile file, or renaming it. I've found some solved problems but they didn't work for me. Maybe I should mention that if I run Firefox from terminal using
sudo it starts fine.
Any idea about how could I solve this?
