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.

cd ~/.mozilla && rm -rf ./*

What that will do is change directories into the ~/.mozilla folder, then delete everything in there, 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

To have some "undo" it's possible to just rename the directory to some other, so it can be undone later, if it's needed. –  LGB Mar 29 '11 at 14:32
    
@LGB - Correct. –  jrg Mar 29 '11 at 14:34
    
When using rm with the r flag, especially when also using the f flag, and especially when providing advice that might be followed by novice users, I recommend avoiding commands that will wipe out the whole home directory if an accidental space is added. In this situation, you can just delete the .mozilla folder along with its contents, by running rm -r .mozilla. –  Eliah Kagan Aug 14 '12 at 9:27

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.
