Vivaldi, 24 days ago @thanhtunoo It's not possible on Android, but if you have a desktop version of Vivaldi, you can use the Sync feature and import/export bookmarks via that. Please file a bug report for it on https://vivaldi.com/bugreport/ and our devs can check if it can be done. If you have an external downloader app installed, you should be able to set it to take over downloads in Vivaldi. See https://tips.vivaldi.net/tip-80/.
