I previously synced my laptop Firefox with my mobile. My mobile Firefox now has all of my laptop bookmarks. My laptop crashed. I bought a new laptop. I want to transfer my bookmarks from my mobile to my new laptop. How?

1- Sync doesn't work because I can't get the recovery key (previous laptop is garbage and the key can not be obtained from the mobile). I could create a new one, but it states that current data will be erased, thus, what is the point of recovery, it is the same as creating a new account. Therefore, I lose my bookmarks by syncing without the old recovery key. 2- There seems to be no other way to export Firefox mobile bookmarks.
