Bookmarks suddenly in library, can't get out

I feel like I am under attack by my computer, or possibly, the internet. I need to do work but instead for a week have had to fix computer problems. I downloaded 'advanced system care'free yesterday, ran it, and now my bookmarks are in the library in a little box instead of under "bookmarks' where I can see a lot of them at once. I have been working on this for hours. Their customer service isn't helpful . Browser is ff, when I tried to sign up for their forum they sent an email that never arrived. Please help me. I have a lot of bookmarks and use them all.

Nevermind, I fixed it In the library I clicked on import, then restore and it worked. Yea!
My over 300 essential bookmarks are now out of the stupid library and under 'Bookmarks', where I can see many of them all at once. All is well.
