You're welcome. As I mentioned, addons.sqlite was superseded by addons.json. This happened with firefox version 25.0. So it only exists on systems which had older versions of firefox installed. The installation here is around 6.5 years old and at this time there was firefox 22. However I rescued the profile from previous hardware so it might as well be more than 12 years. But at this time I probably still used SeaMonkey or even the Mozilla Suite. -- Regards Daniel
