ChatGPT has stopped working in Firefox

Here is how I fixed the issue of ChatGPT not working on Firefox:

  1. Open Inspector tools (right-click → Inspect, or use the shortcut Ctrl + Shift + I).
  2. Go to Storage and delete all local data (right-click on Cookies → Delete All, then do the same with the other options there).
  3. Refresh the page.
  4. Reconnect.
