Cannot install; states that file is corrupt

When I try to download the plug-in, I receive the following message:

I am on a Mac running Sequoia 15.5 and using Firefox 139.0.4.

Is this a warning message from Firefox? It works fine in Chrome, Safari and Edge. I need to download Firefox to test it.

Yes, the message is from Firefox.

Thanks for feedback. It may be related to the format of Zotero plugin, as Zotero itself is based on open source Firefox. The Zotero plugins also use the addon format of Firefox, however Zotero's Firefox engine is relatively old. I need to test and verify it.
If possible, you can change Safari or Chrome to download PapersGPT to use first.
