This Firefox extension should appeal to anybody trying to minimize bookmark and open tab clutter. Read It Later gives you a one-click option for saving the links and keeping track of which ones have been read. It also now sports deep integration with Google Reader.
When you first start the extension, it will prompt you to install the two Toolbar buttons that are used to control the extension and manage your reading list. Users can also control adding bookmarks to their reading list via the context menu, the Bookmarks menu itself, or with hot keys, making access to your daily detritus fast and painless. The toolbar button "Read This Page Later" is great for adding loaded URLs, while the "R" plus left-click hot key was easiest for saving links.
The second Toolbar button manages your "Read something later" list. Click to open a saved page, or hit the drop-down list for more choices. Saved pages can be opened in a new tab or the current one, you can open the entire reading list into new tabs simultaneously, and you can also set the button to open pages randomly or in order. You can also set the bookmark folder that pages are saved to, and users who really want to explore the extension's abilities can play around with the less-stable Offline reading option.
Read It Later ran smoothly and glitch-free, and it is exceptionally useful at simultaneously killing Firefox tab clutter and skyrocketing RAM use while improving your reading habits.
