I wanted to delete Firefox without much experience with Linux. I wanted Chrome to be my default browser, but it doesn't show up on Settings, so I searched with the file explorer 'firefox' and deleted all. Now I want to reinstall it, but it gives me this error message:

$ sudo apt-get install firefox

Open the terminal and type:

sudo cp ~/Desktop/firefox /usr/bin/

The results of apt-cache policy firefox show that Firefox is still installed. Remove everything that Firefox installed and reinstall Firefox.

sudo dpkg --remove --force-remove-reinstreq firefox # remove existing firefox package   

sudo apt install firefox
