Apple's webbrowser Safari offers a great feature called SnapBack. This means that you can save some kind of "waypoint", normally a page containing some links you want to follow. At any later time you can jump back to that page, no matter how many links you have followed so far.

In Firefox you might use different tabs to achieve the same thing. However, I do not like opening too many tabs and whenever I was reading threads in mailing lists and web forums, I missed this special feature. Thanks to free software, I could add it by myself.

SnapBack is released under the GPL (GNU General Public License). It works on Windows XP, Mac OS X and, of course, Linux.

Please see addons.mozilla.org/extensions/moreinfo.php?id=1245 and www.fippu.ch/firefox/snapback.htm for more details.

You may download the curren version (0.5) here.
