Zotero Beta 7 Bug: Annotations buggy and not always visible (no extracted text)
I am using the latest beta version 7 of Zotero.
In the latest version of Firefox (nightly build), you can now highlight text in the PDF and save the PDF with the highlights. When you open the saved PDF in other PDF programs, such as Foxit Reader or PDF-X-Change Editor, the annotations will be displayed normally. However, when the same file is opened in Zotero, the annotations aren't always visible; it just says "No extracted Text" in the annotations sidebar. You can easily reproduce this: download Firefox nightly build, open any PDF in a new tab (drag and drop the PDF into the Firefox interface). Then use the marker in the top right to highlight something on different pages. Save the PDF and open it in Zotero. Sometimes an annotation appears in Zotero but on wrong pages. Often the highlights are not visible at all (No extracted text). The annotations appear correctly when opened in the other PDF programs: They appear on the correct pages and highlight positions.
It would be appreciated if you could fix this. I think this would affect many users who quick edit PDFs in future versions of Firefox.
There are older threads sharing the same issue but with other PDF programs:

Anyway, I tried the latest Firefox Nightly and it indeed produces some invalid coordinates. It works in some viewers, but, for example, Preview.app doesn't display those highlights as well. So I wouldn't be concerned about this until the actual Firefox release. They just need to fix it.
