404-me-not Extension
Searches are triggered by clicking Ok on a popup that automatically shows when a 404 error (page not found) is detected or by dragging the offending link (and optionally the highlighted link text; this requires another extension).
Note: As explained in the demo video, 404-me-not is open source and does not report data about the sites you visit to anyone.
Changelog
---------
v. 1.1.0 -- If install is an update don't display options.
v. 1.0.0 -- Code cleanup. Changed parsing behavior so trailing URL slash, page extension, and query strings are always ignored.
