Corrupted addons on Firefox (Zotefile, Zutilo, Zotero-ocr)

Hi all,

I have been trying to install these three addons on Firefox 74.0 for Zotero 5.0.85: Zotefile, Zutilo and Zotero-ocr.

For each of them I tried to find the newest version (Zotefile here: http://zotfile.com/ ; Zutilo here: https://github.com/willsALMANJ/Zutilo/releases and Zotero-ocr here: https://github.com/UB-Mannheim/zotero-ocr/releases)

Alas! Each time Firefox keeps sending me this message while trying to install them : "This add-on could not be installed because it appears to be corrupt."

I tried to install them via the downloaded .xpi file, but it still doesn't work

After various researches including on the Zotero forum, I couldn't find a solution to this problem.

Do you have any clue to help me install these precious addons?

Thanks a lot for your help,

Gabriel
  • You need to install these add-ons in the Zotero desktop program, not in Firefox. In Zotero standalone, go to "Tools" -> "Add-ons" and select "Install Add-on From File..." in the gear menu in the top right.
  • It works indeed, many thanks for your quick help!
