I am trying to locate saved bookmarks on a OS X slave drive that once used Tor. Where are Tor bookmarks saved in the OS X file structure?
The bookmarks are stored in an sqlite database inside the application bundle. If you right-click on the Tor Browser application and then select "Show Package Contents" from the context menu, you can see the folder structure inside the package.
The database is located at TorBrowser.app/TorBrowser/Data/Browser/profile.default/places.sqlite
You can query (for example) the titles and URLs like this:
sqlite3 /the/path/to/your/TorBrowser.app/TorBrowser/Data/Browser/profile.default/places.sqlite "select moz_bookmarks.title, moz_places.url from moz_bookmarks, moz_places where moz_bookmarks.fk = moz_places.id;"
