Override to make it work Rated 4 out of 5 stars
Simple but useful add-on. Unfortunately it hasn't had an update in a long time. I have to use Nightly Tester Tools add-on to override the non-compatibility warning.
EDIT: Okay, they stopped allowing Nightly Tester Tool as a way to force install of old add-ons. Just turn off the compatibility check and manually edit the install.rdf file. Give it a max-version well into the future.

Pretty good. Captures shot of entire page including what is not viewable because it is long. No need to do several screen captures and having to stitch them together.
Down side: it seems to cut off a few pixels on the sides. Also, author's web site (right-click on extension) is bad link and web site listed on Firefox add-on site doesn't mention Webshots so difficult to find help on the options available for this extension.
