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.
Hi, 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. Firefox: 46.0a2, Build ID: 20160203004041, User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:46.0) Gecko/20100101 Firefox/46.0
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.
For me the bug is resolved with firefox 54.0.1 (64-Bit).
