The problem does not happen in non-e10s window.

Steps To Reproduce:
0-1. Make sure install Adobe Reader
0-2. In about:preferences#applications, Set "Portable Document Format (PDF)" of content type to "Use Adobe Reader (default)"
1. Open http://ybb.softbank.jp/support/connect/adsl/setupguide.html
2. Click a pdf link (i.e, "Step 1 (2.53MB)" etc. )

Actual Results:
The pdf is opened with Adobe Reader as expected.
However, An empty tab is remain opening.

Expected Results:
The pdf is opened with Adobe Reader as expected.
Then, the empty tab close automatically.

Same thing happens on OS X with opening links from Terminal.app. Works fine with non-e10s windows but with e10s enabled I get an empty tab. The tab however does have the correct URL set as it's title.

I have tested this on latest Aurora (46.0a2) release and I have managed to reproduce it with e10s enabled. I followed the provided steps and with e10s enable after I clicked the PDF link an empty tab it opened but does not close automatically. With non e10s the empty tab close automatically.

I also encounter this bug with firefox 50 (since 47 or 48). (on debian and windows too)
A lot of our users (i'm developper of a JEE accounting web app) are complaining about this bug.
We have discovered a way to correct this :
in about:config, change extensions.e10sBlocksEnabling and extensions.e10sBlockedByAddons to true. (it's simply disable e10s)
This is clearly not a good solution. We could do this change for our internal users, but not for our customers.
Did a patch is in good way for this bug ?

I can confirm this bug on Win7(64bit). It first happened to me when I updated to firefox 50.0 (64bit). Now with firefox 51.0.1 (64bit) it is still there. I often open PDF links out of a web application to show it in external Foxit Reader. Since ff50.0 every opened PDF leaves open an empty tab. In previous ff version this empty tab would appear only for a second and then close automatically. My solution to this bug I got from Camp Firefox:

In about:config, change browser.tabs.remote.autostart.2 from true to false. This will disable e10s.
