Save to Zotero on a web page of the "PDF Viewer" extension

I once installed 3rd-party PDF Viewer extensions, like and The second one can work with Vimium C's shortcuts, which is more convenient than Chrome's private PDF viewer.

But Zotero Connector doesn't recognize such tabs and its browser icon will do nothing when I click it.

I think it's possible to add supports for these extensions - maybe just need to add a simple advanced option - because they put PDF links into their URLs, like:
* chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/
* chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/content/web/viewer.html?

Then an option to parse real PDF URLs from those matching specified prefixes would be enough.

Any ideas about this?
  • Hello. I changed some code of PDF Viewer for Vimium C, and makes it embed its PDF viewer iframes into normal PDF tabs. So, now it seems to work well with Zotero extension.

    Then this discussion can be closed.
  • Hi, may I ask how did you modify the code of PDF Viewer? I have the same issue. Thank you.
