About this extension

Who Wrote That? (WWT) is a browser extension, which displays authorship information directly on Wikipedia articles. When you hover over content, the tool highlights all content by the same author. When you click on content, the tool identifies the author of the revision, along with revision details. Overall, WWT allows users to discover the source and background of an edit, without digging through revision history.

Developer comments

The source code for this add-on is managed on Github at github.com/wikimedia/WhoWroteThat.

To generate the XPI, run `./node_modules/.bin/grunt run`. Afterwards the ZIP files should be in ./dist/extension_firefox. This also opens up a Firefox window for testing, but you can simply close it.
