I've recently been using Zotero with the Zotfile extension, and have been very pleased with the overall system. However, I have been unable to extract annotations from PDF files.

Setup:
Macbook, OSX 10.4.11
Firefox 3.6.28
Running Zotero 3.0.3 (as Firefox Add-on) and ZotFile 2.1

I have tried to extract Annotations added through Preview (ver 3.0.9), however I get an error message:
- "...not supported with Firefox 3.6..." when attempting with pdf.js

or
- "Annotation extraction failed" when attempting with poppler (ver 1.1)

I was hoping for some recommendations to help fix this. I'm afraid that it's going to be "Get a new computer with a current OS" - i'm at the most current version of firefox I can run with 10.4.11

In the meantime, I'm using Skim, which works fine, but as I understand from browsing these forums, won't work with Zotfile for annotation extraction period.

Appreciate any help you can provide.

Thanks,
-J
