Fix an issue with my firefox / google addon

Hello everyone! I have built an addon that is giving me some small issues. I am looking for someone to help fix my addon so that it works correctly when someone pushed the back button. At the moment it works perfectly UNLESS the user clicks the back button. It will take someone about 10 - 15 minutes for someone who knows what they are doing. I would like to have the code changes explained to me via skype or instant message.
