The browser extension

Every version of the HARD extension.

Each zip here is exactly what we released for Chrome, Edge and Brave. Its fingerprint is the zip’s SHA-256: if yours matches, it’s the file we released. On a Mac, check one in Terminal with shasum -a 256 ~/Downloads/hard-chrome-1.0.0.zip.

The Chrome Web Store re-packs what it installs, so a copy from the store won’t match these fingerprints. Check that one by its version instead: find HARD at chrome://extensions. In Edge it’s edge://extensions. Firefox and Safari are coming. Every HARD app’s versions.
