I wanted to contact you to ask you if when Firefox automatically updates to a more advanced version or an entirely new version if the personal custom settings that i have made will be reset to their default settings or change in anyway as i dont want to have to check every time after there has been an update made to see if the settings have indeed changed or not and also having to change them back to the way i want them to be if they have changed so please get back to me and tell me about this issue, thanks.
