I use Chrome and Firefox to view PDFs online almost every single day. However, from yesterday I noticed that PDFs cannot be opened in both of them. The only browser can open a PDF document online is Safari.

This is the error that I got from Firefox when trying to open PDFs:

[18:56:30.824] Error: Bad end offset: 940 @ resource://pdf.js/build/pdf.worker.js:126

I did an experiment by trying to open PDFs from "Google filetype:pdf". The result shows that the above situation happens on almost every PDF document (over 99%).

Below are my configurations:

  • OS: Mac OS X Mountain Lion.
  • Firefox: Firefox 25.0.1
  • Chrome: Chrome 31.0.1650.63
  • Installed PDF Reader/plugins: The built-in Apple Preview. No other PDF readers or plugins.

Does anyone encounter the same problem? Is there any solutions to address this?

Thanks for your suggestion. I saw the above thread early before. However, it is not relevant and does not solve the problem. :-( –  Slash_D Dec 4 '13 at 20:00
    
Has your machine always had this issue with FireFox? If not you may want to try running the Repair Disk Permissions under Disk Utility. You can also try to re-install firefox –  falconspy Dec 4 '13 at 20:02
    
Hi Falconspy, thank you very much for your suggestions. However, even after I repaired the disk permissions and reinstalled Firefox and Chrome, the problem is still there... :-( –  Slash_D Dec 4 '13 at 20:16
