Users of firefox may already know that you can add all sorts of widgets to it that enable all kinds of useful extra features.  We’ve just found a great tool that will make your life so much easier;

Xsticky Notes

Add this to Firefox, and it allows you to put a sticky note right onto a webpage, that will be there when you revisit it. A great use for this is where you lookup a few different websites, and need to ring the companies behind them and get more information; Just use this extension to take notes during each phone call, then those notes are saved right on the webpage, so you can refer back to them quickly and easily.

Give it a try!
