please, add some basic usage instructions.
can't find that button...
I only wanted the "expand older history" functionality and that works (and still works).
The script runs but it didn't delete any of my wall history.
Installed into greasemonkey for FF 5.0. Couldn't find the 'tempting' button so went to 'user script commands...' in greasemonkey and clicked on 'delete all wall activity'...nothing happens.
Appreciate the effort though.
