When a user on a Chromium-based browser has the Zotero connector extension enabled, ePUB titles on the ProQuest Ebook Central Platform do not display content. Example: https://ebookcentral.proquest.com/lib/vcu/reader.action?docID=31339340&ppg=1

As soon as the connector is disabled, the content loads without issue.

This issue can be recreated on Mac and PC, on Chrome, Brave, Edge. Issue does not appear on Safari or Firefox Browsers.

PDF-based titles on this platform do not encounter this issue and load normally

    Is that Edge with the actual Edge extension, or did you install the Chrome extension in Edge?
  • tjsiegelvcul
    It is the extension that you linked to. The other browsers use the extension from the Chrome Web Store

    We can only offer troubleshooting for Chrome or Edge. Can you provide a Debug ID for refreshing this page from the Zotero Connector?

    If you open the same page with the Connector extension disabled and enabled and open the Developer Tools, do you see any additional errors in the Console?
  • tjsiegelvcul
    Yes, there are 2 additional errors when the extension is enabled vs. disabled.

    1 refers to the extension restarting, then the other is:

    Uncaught (in promise) SecurityError: Failed to read a named property 'document' from 'Window': Blocked a frame with origin "https://ebookcentral.proquest.com" from accessing a cross-origin frame.

    Hi, this is happening to users in Chrome but not Firefox and Edge. It only happens to EPUB titles, not PDFs.

    I contacted Proquest about it and they said to just disable the extension if I want to see full-text for EPUB. Modifying the site data permissions for the extension also works.

    I work for a university library and this is going to be confusing to explain to users. Is there a fix in the works? Is this something Zotero needs to fix, or Proquest?

    Thanks!
