Grammarly Extension Not Showing

Workaround available Chrome, Edge, Firefox, Safari Updated October 21, 2026

Quick answer

If the G icon is missing from text fields, the extension is usually unpinned, switched off (gray icon), blocked from reading site data, or replaced by the desktop app or Superhuman Go. Pin it, turn on 'Check text with browser extension', and allow it on all sites.

Most likely fix: Pin and enable the extension.

Symptoms

No green G in text boxes or the toolbar, a gray G icon, a gray Wi-Fi icon instead of the G, or Grammarly working on some sites but not others.
