Okay so last year I built myself a new desktop PC around August 2020. I was using an Android smartphone prior to that and had some bookmarks on it I wanted to transfer to the desktop. I mistakenly thought it would simply 'absorb' those Android bookmarks into the bookmark collection I already had on this new desktop, but after using sync, it straight up removed the desktop bookmarks that were there and replaced them with the android ones exclusively. Another neat little 'feature' is how the bookmarks were also completely erased from the Android device after this.

So once that happened, I restored my old desktop bookmarks, but then the bookmarks that were imported from the Sync from the android were now gone. My question is this: are those sync'd android bookmarks actually anywhere at all, like did Firefox automatically archive them somewhere just in case, or are they just lost completely? Thanks.
