Zotero 10: duplicate reference import using Zotero connector

fjdiezguerra · 2026-08-27T21:06:18+00:00

I am experiencing duplicate reference (and pdf) import using Zotero connector in Firefox.
I am using Zotero 10.0.1, Zotero connector 5.0.212, Firefox 154.0.1 (64-bit), and Windows 11 Pro for Workstations 25H2
Also, I have installed the following plugins: Better BibTeX for Zotero, Linter for Zotero and Scite Zotero Plugin (V7+).

We'd need a sample URL where this happens. If this happens across multiple sites, we'd also want you to test in troubleshooting mode (Help menu)

I have just come across this duplicate issue with the following url: https://www.nature.com/articles/d41586-026-02663-6?utm_source=Live+Audience&utm_campaign=979755b2c6-nature-briefing-daily-20260827&utm_medium=email&utm_term=0_-33f35e09ea-49888408

However when I change to troubleshooting mode the imported reference is no longer found as duplicated. Further, in troubleshooting mode the duplicate issue does not occur.

When I return to normal mode and disable the linter for Zotero plugin I get again duplicate import, for example with this url: https://www.nature.com/articles/d41586-026-02616-z

After further investigation, it seems that the duplicate reference is something temporal or transient. When I search the same reference across the whole library I only find one reference, not the same duplicate reference.

I have never observed this before. I should also say that I have a big database of around 38K references.
