Selenium allows you to bookmark websites for quick access at a later date.
Browse to the website you want to add to your bookmarks.
Choose Browse > Add Bookmark, or press Command D.
A sheet will appear attached to the main window. Rename the bookmark if you wish, and choose a collection to place it in from the popup button.
Click the Add Bookmark button.
The website will be added to the bookmark collection you chose. Bookmarks are saved on a per-project basis; if you do not see the website you bookmarked in the list of bookmarks, make sure you are working in the same project as you were when you bookmarked the web page.
