Bookmarks dissappeared, library shows no saved bookmarks, I want to import from my IOS

My Firefox has lost its bookmarks and I dont know why. I tried following the steps for restoring them, but choosing "restore" in bookmarks library just shows "choose file" and then nothing happens. When I check my phones firefox, they are still there so I was wondering if I can import from there, or if anyone knows a fix? My computer is a Macbook 2017, phone is a iphone 15.
