Taboo is an open source Firefox extension that lets you save a tab for later. It takes a snapshot of the web page, including session state information, like: as how far you've scrolled on the page and information in forms. Later you can reload the tab by searching/browsing through all your saved tabs. A single click and you're back to the same place in the article.
Searching through saved tabs (url/page title) and a tooltip with a larger screenshot of the page help you find the tab you are looking for. When you want access to one of your saved tabs, click on the other Taboo button, and Taboo will load thumbnails of your saved pages into a new tab. From there, all you need to do is click on a saved page, and it will automatically load, complete with scroll location and any text you may have entered.
