Extension Usage Instructions

404-me-not saves you time by making it extremely easy to search for missing webpages. It will search both the Wayback Machine (a huge database of archived pages) and whatever search engine you choose, using the last part of the URL and keywords you supply as clues.

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.
