When I click on "Other bookmarks", I get about 10 items that say "Bookmarks bar" and another 30 that say "Favorites Bar" and still more that say "Delicious-do_note_delete".
Q: How can I clean up my Bookmarks bar?
1 Answer
Use Bookmark Manager.
Open it by entering chrome://bookmarks/ in the address bar or by clicking on the Customize & Control button i.e. ⋮ on the top right corner then select Bookmarks and then Bookmark Manager (⋮ > Bookmarks > Bookmark Manager).
Here you can delete/modify/edit all or desired bookmarks. Select all shortcut, i.e. Ctrl+A, may come in handy if you want to delete all or most of your bookmarks.
