Extension wouldn't show an extension button to click. *EDIT* It does work. The "extension button" is in the address bar and not where all of my other extension buttons are. I suggest you clarify you "about" instructions to state where the button is.

Does what it is supposed to do. 2-minute SOC code display in the FF bar once installed and logged into your T-Mobile account via FF.

Worked as detailed, made finding the SOC really easy, thanks!
