Outdated and incompatible at least for FF 6.0 Rated 3 out of 5 stars
A very interesting AddOn, which helped in some special situations really good.
Unfortunately it seems to be incompatible with newer versions of FF, on its own website one can see it as to be on version 18.104.22.168, though here there is only 22.214.171.124 available... and nobody seem to recognize it - is it dead?!?!?
That's a pity!
