Do you want to access Google Chrome Bookmarks from the sidebar? Chrome’s bookmarks place in a bar below or under the URL bar. You can select to hide or show it using the Ctrl+Shift+B keyboard shortcut. The bookmarks bar can’t display all bookmarks and they move into a menu where you can scroll through them. Also, you can open the Bookmarks’ Manager then access them from there. Many other browsers can do it quite differently; they can just add the bookmarks like a side panel. If you want to get a Chrome bookmarks side panel, you can then get it using an extension known as Bookmark Sidebar.
