Currently firefox for android only allows syncing bookmarks between devices using firefox sync. There is no option to import them from or export them to an html file. The desktop version allows this.
The problem is that not everyone wants to sync bookmarks. I just want to backup them locally when switching custom ROMs and firefox doesn't allow this. Also, this would make switching to firefox easier for people as they can import bookmarks from other browsers.
It would be great if Firefox add this on android and maybe on iOS too if it's possible there.
