I would like to restore bookmarks to their state as of a certain past date and have a time machine backup from that date. In which system folder are the bookmarks stored? I am running Mac OS X High Sierra 10.13.6.

Thanks for the help. I checked the indicated path before but didn't see what I wanted. Making invisible files visible (shift command period) was the answer.
