For the Firefox users:
Found an interesting page but want to read the page afterwards, because you are busy right now?
I came across the add-on: Taboo.
This is specially useful because you do not want to keep in to delicious and also do not want to bookmark it. Well, taboo is a kind of bookmark.
Bookmark for temporary use with visual preview.
I have put my regular pages I visit on Taboo preview and is really useful + easily accessible.
The description provided by them:
If you keep tons of tabs open because you want to continue reading them later, Taboo is for you. Taboo lets you save a page for later (taking a screenshot, and using the Session Saver code to remember scroll location and form fields).
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.
