I just donated for the very good last version and today all settings are destroyed for a absolutely unusable updated version - wished I wouldn't have done so! The last version urgently needs to be downloadable again.
Sorry, but the statusbar/addonbar is missing in new versions of Firefox. The current version of Forecastfox is the version for the new API: WebExtensions
But I'm not guilty - these are the inevitable changes in Firefox. All Xul-addons is die in Firefox 57 (November 2017) https://blog.mozilla.org/addons/2017/02/16/the-road-to-firefox-57-compatibility-milestones/
