Changes

A Firefox Extension which overrides 404 pages and supplies information from Google Link Doctor can be found [httphttps://sitespeople.googlemozilla.comorg/site~beltzner/cbartley2017/etctemp/friendly-error.xpi.zip here]. Note that the 404-override mechanism is currently pretty crude, and it just has a test UI for displaying all the data returned by Link Doctor. I've only tested it on Firefox 3.5, but it should probably work on Firefox 3.0 as well. It's safe to install it on your default profile, but you may not want to leave it installed.
