Hello, thank you for the great extension. I have been using this extension for the past few years. My only problem is the ability to sync data between different browsers. For example, between Firefox, Vivaldi, and Opera. It is difficult to transfer manual backups between these browsers. An easier solution for syncing data is to upload data to Dropbox or Google Drive, which would be great if added. Sync to a WebDAV server has its own problem and is not easy to set up. Although I enabled the data sync option through the browser, once Firefox was reset, the smartproxy data was completely deleted. Thanks
