I know some of you folks use the Killfile script I wrote for Firefox so
figured you'd like to know that I've updated it and you can get it here
http://www.penney.org/google-groups-killfile-20.html
It's much the same as the old version only it now works in the thread
view as well as the index view and is much smarter about how it figures
out where to insert the ignore user links (it was a little buggy
previously)
Anyway hope you get some use out of it.
