Suppose you have a Chrome extension that has an Options page, and this Options page has a link to an external address (e.g. http://www.google.com). Now if the user clicks that link to open http://www.google.com in the *current* tab, and then click Chrome's "Go Back" button, the user will see "Unable to connect to chrome-extension://invalid/".
I know this is due to Chrome's security paranoia. My real problem is that I have a PDF file inside my extension and this PDF file has a link to an external address like the above, and Chrome's built-in PDF viewer can only open the link in the current tab, and when I go back, I see the error message described above.
Any idea?

If I host the PDF file on a website rather than include it in the extension, "Go Back" will function well. But I wonder if I can somehow put the PDF file in the extension and still work around that error message.

This is actually a bug. It should be fixed by http://crrev.com/150606 (currently just in the Canary channel).

I found a solution! Just put that PDF file in manifest.json's "web_accessible_resources" :-)))

what happens if you declare the pdf in the manifest as:
{
...
"web_accessible_resources": [
"somedoc.pdf"
]
...
}
That solved my problem in instances like this.
