Status: RESOLVED DUPLICATE of bug 1374025

(Firefox :: Tabbed Browser, defect)

Description

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:56.0) Gecko/20100101 Firefox/56.0 ID:20170621030208 CSet: e1e4a481b7e88dce163b9cccc2fb72032023befa

Whenever I tear off a tab its content get reloaded. I noticed that when working with one-click loaners via Treeherder.

Steps:

1. Open https://tools.taskcluster.net/one-click-loaner/#Tcn9ZzzhSoS4WSmOh7oZ4g
2. Login and create a one click loaner
3. Wait until the loaner has been created
4. Open a root shell or a VNC screen
5. Tear off the tab

With step 5 I only see a white page with nothing loaded. Any running shell or VNC connection is lost.

Feels like a dupe of bug 1374025.

By doing the above steps the following error is visible in the browser console:

It's the same behavior for those pages, indeed.

I'm a little confused why I was copied here -- I don't know what it means to "tear off a tab", but I don't think it has to do with Taskcluster... anyway, seems there is agreement it's a dupe..
