Hi Alex, thank you for the feedback. The difference of the apps is huge in terms of the technology. The new add-on is a stand-alone app which you can use without the desktop app which was not the case previously. Also the new one is built in compliance with the new Manifest v3 requirements which makes add-ons safer, more efficient, and better for your privacy. Unfortunately for developers it means that the add-on must be rebuilt almost from scratch and that's what we did recently. We are sorry for the inconvenience while we tirelessly try to improve the app every day. We believe that the new app if not today then very soon will bring way better experience than the old one.
