It pains me to see this Add-ons go.The reason i used firefox is because of great addons like this.Will definitely donate if the author wanted or needed any financial help.Developer like this guy deserve all the funds he needed.Infact FFox should pay him for developing such an essential addons.Thanks for everything Button Guy
It is not totally gone, I have released a number of the buttons from it as separate extensions, and I am trying to release more all the time. If you post to my forum with those that are particularly important to you I might try to do them sooner rather then later.
