Browser bookmarks (favourites, in Internet Explorer) a powerful, free tool
This is something I only realised the other day. Now I cringe to think how lost I'd be without it.
Organize them
Like so many powerful tools out there, bookmarks are only as useful as you make it to be. If your bookmarks look like it's been washed in a tumble drier, don't expect them to help you be a more efficient human. Take the time to create different folders for different websites, and make sure you group them, and that you are grounded in this habit.
Save them... just in case
Any good browser has the 'export' option for your bookmarks. This is a great way to make sure you do not lose them, should your computer decide to die. In Firefox you'll find this option under the 'Bookmarks' tab. In Internet Explorer 7, you need to click on the 'Add to favourites' button.
Import them into your favourite browser
Any decent browser gives you the option of exporting your bookmarks, which you can then import into a different browser. This is very handy if you have to work at different machines, and you don't want to have to remember from memory where you got that sweet deal on a chewbone for Fluffy.
