Morning Coffee is a firefox addon which can save your website navigation time by keeping track records of yout daily visited websites and opens then in tabs. These websites are recorded according to the days of week. This is really handy if you read sites that update on a regular schedule (like webcomics, weekly columns, etc.).
Morning Coffee in action
As you can see in the screenshot, its somewhat similar to bookmarks and latest update allows separating lists by time (so you can have a morning/afternoon list for a day, for example) It is good for those who do not use feed reader or something like that or for the websites whose regular reading is not must.
