I am facing this error when I start firefox

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I just installed ubuntu so I do not know what's wrong with it. I am using chrome now. I must use sudo firefox to start firefox which is very troublesome.


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

firefox -profilemanager

When the window opens, delete the profile, and create a new one.
