Not without an add-on (I'm not sure of one that does that either I am afraid).

Would the Bookmarks side-bar help? You can do this by clicking the Bookmarks icon and then selecting View all Bookmarks. Also you can press CTRL + B

If not you can also show the bookmarks toolbar which will put a list of your bookmarks underneath the address bar. This is done by:

1. Click the Settings button (three horizontal lines in the top right)
2. Click Customize at the bottom
3. Click Show hide toolbars (at the bottom) and then select Bookmarks Bar

Hope this helps

You can organize your bookmarks in folders to avoid scrolling down.
