ok I downloaded about 10 debian packages for Iceweasel 3.0.6 and have it working on 4.2. It has the same issues on puppy 4.2 as firefox 3.0.6, if you goto
https://addons.mozilla.org/en-US/firefox and try to move the scroll bar up and down it drags terribly, the mouse is at the top of the page and about 30sec later the scroll bar reaches, I did try last week replacing, glib,gtk2,cairo,pixman,pango and then compiled firefox and the same issue happened, I also updated flash to 10 and the same issue.
