great tool Rated 4 out of 5 stars
i definitely love this add-on
the only problem that i encountered so far is
thet when iMacros (0.8.0.2) is installed with the Stealther Add-on (0.98)
Firefox does not accept cookies anymore.
It works when you manually set it again after every reboot
of the Browser.
When installed seperately everything works fine as well.
