How to delete and create a new firefox profile from TTY1?

To delete all Firefox settings type:

mv ~/.mozilla ~/.mozilla.backup

in a terminal. On next startup Firefox will create a new ~/.mozilla directory for a new session with default settings.

To restore your settings type:

mv ~/.mozilla ~/.mozilla.newbackup
mv ~/.mozilla.backup ~/.mozilla

This way you can create a variety of settings to restore when needed.

WARNING: This will delete everything in the Firefox config - there is no undo.

With that out of the way, to do that, you can run the following in the terminal.

rm -rf ~/.mozilla
rm -rf ~/.cache/mozilla

This will delete local settings and cache, including the extensions.

EDIT: Thanks to one of the comments, there is a way to backup the firefox config. To do that, follow the line below instead.

cd ~/.mozilla && mkdir backup && cp -r ./extensions ./backup && cp -r ./firefox* ./backup && rm -rf ./firefox* ./extensions
