Resetting Master password

[edomoga1981]

Hi, I have been using this fine addon for years on Firefox, mostly to block reddit from myself during work hours. I would like to add more sites to it, but unfortunately I forgot my master password.

In the addon options menu, I cant even check the "Do not ask for the master password to block a new hostname" , because it would require the master password to save the newly changed options.

Is there an option to reset my master password, without resetting all my addon data and settings on Firefox, or a way to have changes in options that add rules not require the master password?
