Below are two firefox add-ons productivity tools that should make your life a lot easier :
QuickFox Notes :
This is a note-taking add-on for Firefox that saves notes as bookmarks in Firefox. This means you get all the convenience of browser-based note-taking, and cross-browser syncing if you’re using Mozilla Weave, Xmarks, or another method to sync your bookmarks between instances of Firefox.
Read It Later :
Read it Later is an extension that works with a Web-based service. Here’s how it works. Once you install the extension, RiL adds a yellow icon to the “Awesome bar” in Firefox, and a similar icon to the toolbar next to your search. When you’re on a page you want to save for later, just click the yellow icon.
Google Reader fans will also love RiL because it will also clip items from Google Reader without having to view the page first. Once the extension is installed, it adds a RiL icon to Google Reader items (right next to the star). Just click that and the entry will be added to.
