Firefox users may notice a “Returning Reader?” banner showing up at the top of the main page sometimes. This is a link to the highest-numbered page you’ve read so far (remembered as a cookie in your browser).

Right now it’s a Firefox-only thing, but I’ll try to get it going in other browsers as well. Let me know if you find it convenient.

Update: turns out the problem was that I was specifying application/javascript in the <script> tags rather than text/javascript. It should work on all the major browsers now.

Update: if you’ve got Firefox and Greasemonkey, the indefatigable ecmanaut has written a userscript which does roughly the same thing for most any comic (with some tweaking—it doesn’t work out-of-the-box for The Last Bus yet).
