It works for me in FF 8.0.1 :) Rated 5 out of 5 stars

It works perfectly for me with no bugs after editing the intall.rdf contained in the *.xpi extension file. First I changed the *.xpi to *.rar and then open the install.rdf file, and I changed the maxmem vervion of FF to 10.0 and it works also with FF 9.0 beta 6 (tested today by me). Images are saved in both .jpg and .png, full or partial image and everything's fine.
