I recently installed 16.10. I have some problems with browsers! The Chromium only works when I open a new window with a temporary profile and Firefox gives this error:
Your Firefox profile cannot be loaded. It may be missing or inaccessible.
and the only way to run Firefox is running sudo firefox with Terminal.
I removed and installed Firefox again but it didn't solve problem.
Does anyone know why this is happening?
Given you have run Firefox with sudo, and probably other programs not meant to be, you need to regain the ownership of files in your home directory so they are accessible without root permissions again. This is why you are getting the error:
Access was denied while trying to open files in your profile directory.
If there is any output from find ~ \! -user $USER, and I'm sure there will be, you need to run the command:
sudo chown -R faezeh:faezeh ~faezeh
