View diffs of files and directories on GitHub.
To use this extension, go to a file or directory in GitHub and click the **History** button. Then, click on any commit. The extension will override the click to show the diffs of only the relevant files instead of GitHub's default behavior of showing the entire commit's diff. This is especially helpful when a commit is very large and GitHub only shows a partial diff or none at all. To get the regular view, simply refresh the page.
