pdf viewer wrong line highlighted

more options

When I highlight specific text in the pdf viewer in Firefox for Windows and copy it the wrong part gets copied instead of the highlighted text. I copy the text 2 lines under the highlight. I have the problem only with specific pdf, for example with an ISO from breuth. When I use Adobe Acrobat, I don't have the problem. Maybe it is a software bug?

Hi Alex, if you have a bit of time:

The latest version of the PDF viewer is developed on Github, and there is a demo of it here:

https://mozilla.github.io/pdf.js/web/viewer.html

You'll notice on its toolbar, just to the left of the printer icon, an extra button to Open File so you can test locally saved PDFs. If the bug still exists in that version, you could file an issue for the problem on Github:
