I do not use a computer at home therefore I am unable to sync my bookmarks that are saved on my Android phone. I searched everywhere for ways to create a back up and found nothing. Many other people want and need this capability. Even those who use sync have lost mobile bookmarks during sync operation and want to back up on their Android before synchronizing. There are plenty of people who want this feature but. All Mozilla has to say is use sync but that is not acceptable. Most of us came to Firefox because we didn't like Bill Gates or anyone else telling us how to use the web. But now Mozilla Firefox is doing that very thing by not giving us a necessary and fundamental tool within the Firefox browser.
