Sidecar Bookmarks Sidebar is a Chrome extension that provides a simple bookmark sidebar that stays open while you browse. If you miss the Firefox bookmark sidebar, this extension is for you.

The main features of Sidecar Bookmarks Sidebar include a tree view that can be opened and collapsed at your request, the ability to search your bookmarks in the sidebar, and the option to choose whether you want Sidecar to stay open or open on demand. You can also add the page you are on as a bookmark to any folder in Sidecar. The sidebar can be easily opened and closed with a button on the browser toolbar or with a custom key command.

Unlike Firefox, Sidecar Bookmarks Sidebar opens on top of the page instead of pushing it over to the right. This is because Chrome extensions do not have the same allowances as Firefox. However, users have reported that the easy ways to open and close Sidecar make up for this inconvenience.

Updated on January 26th, 2015, the latest version of Sidecar Bookmarks Sidebar includes an optional tab on the left side of the browser and various bug fixes. The tab provides a convenient way to open Sidecar quickly.

Overall, Sidecar Bookmarks Sidebar is a useful extension for Chrome users who want a bookmark sidebar that stays open while they browse.
