Taboo lets you save a tab for later. It takes a snapshot of the web page, including session state information (such 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.
Tab Mix Plus
If you are a Tab Mix Plus user, this extension requires the built-in session manager. You can tell Tab Mix Plus to use the built-in session manager via Tools->Session Manager
