Claudemessages cells fail to update with Firefox in Tutorial Spreadsheet

Thanks a lot for this tutorial. It is very well made, and I learned a lot!

In Firefox (132.0.1) the claudemessages cells fail to update after a change in the prompt cell. See error below:

I followed the steps to setup the plugin and API key as described in the spreadsheet and it works well in Google Chrome. Just not in Firefox (tested without plugins/adblock).

Workarounds:
1. Refresh the page. The claudemessages cells will update correctly, sometimes it needs 2 refreshes.
2. Use Google Chrome - everything works fine there.
