I use a Firefox extension called NextPlease which allows me to use the keyboard to go to the next or previous page on web pages which have Previous/Next paging links. Like the Google search results. I downloaded a version from http://cisengineer.com/firefox/ for my Windows XP. On a Windows 7 FF 3.6 machine, Firefox can't import the extension because it's not compatible with FF 3.6 even though it worked in FF 3.6 in Windows XP.
Is there an update to this extension or is there a similar extension? I downgraded to FF 3.5.7 to have the extension working.
