question

My tablet was my mother's old one and I used it while it was still under her acct. Once I realized that, I un-registered it and lost all of my apps, bookmarks, pics,etc. Fast forward 2 years.

My fire tablet (5th gen) is slowly declining and freezing alot which has prompted me to save all my pics, vids, etc to my computer. I still haven't registered my tablet. I want to import my bookmarks from Silk to my computer or to a new fire tablet once I purchase one. If I can import from Chrome (which I don't have) why can't I export/import to another app or computer like all the others allow you to do? If I choose to register my tablet now, will I lose all that info and settings again? I have a ton of bookmarks that I would rather not input manually.

Thanks
