Bookmarks (or Favourites) ?
Every browser has the capability of creating and saving bookmarks, these are links to web pages. Once you have a bookmark all you have to do is click on it and within a second or two (depending on your internet connection and how the web is feeling that day) you are back at that page.
You don't say which browser you are using. IE calls them 'Favourites, Firefox and Chrome still call them 'Bookmarks'.
In Firefox, either click on 'Bookmarks' then 'Bookmark this page' to create a bookmark if you have the menu bar visible. If you don't, click on the star icon at the right hand end of the address bar and this too will create a bookmark.
Chrome also uses the star in the address bar to create a bookmark. At the moment I do not have a computer up running Windows so I cannot speak for IE as I almost never use it but it uses a similar system. Another advantage of bookmarks is that you can back them up to an HTML file so you can back them up as part of your normal backup program.
Bookmarks are a great invention, I guess I have between 3 and 400 on my system ! On a personal note I would not use a toolbar no matter how innocuous or useful. Almost all of them just use up scarce and valuable desktop space for very little benefit ! But this is just my personal opinion.
