[Zotero extension +] Firefox v116 on macOS broken Discourse?

Then that should have been made clear before the subject line amendment.

And while Zotero have admitted they caused a problem it is possible that other browser add-ons could cause the same problem. It is too specific to have Zotero in the subject line.

A better amendment would be “Browser add-ons (including Zotero) in Firefox (after updates (e.g. v116)) may break Discourse”.
