Hi As one of our developers recently explained, browsing information like history, bookmarked sites, and cookies isn’t accessible to third-party browsers on Android. This data is kept within a web browser application’s data directory, which isn’t directly accessible to third-party browsers, and there’s no API or ContentProvider to enable it to be imported. Until Android is able to support this, this support document might help: https://support.mozilla.org/en-US/kb/importing-bookmarks-firefox-android (Covers bookmarks and passwords.)
