A settings export/import feature allows users to save and transfer their configuration settings across devices or environments. Users can export settings to a file (e.g., .json or .xml), and then import them into another setup. It enables easy migration, backup, and sharing of settings. The process includes an export option to download the settings and an import option to upload the file. Security features like encryption can be added for sensitive data. Would you like more details on how to implement this?

Yes please, I looked and didn't see how this was possible for Firefox Klar/Focus.
