OctoPermalinker ★3
OctoPermalinker is a browser extension that searches GitHub comments/files for links to files on branches, and adds a link to where the branch pointed when the comment/file was made/updated.

For example, suppose you’re looking at a gist that links to a file on the master branch of a repo. At the time the gist was made, the link worked, but if the file gets removed, the link is broken. OctoPermalinker uses the gist creation date to add a permalink that still works. Here are some screencasts demonstrating the difference:
