1303911 - restoring a single container tab quickly opens a second tab that disappears instantly

Status: NEW

(Core :: DOM: Security, defect, P3)

Description

[Kamil Jozwiak [:kjozwiak]]

When restoring a single container tab while using "Show my windows and tabs from last time" under about:preferences#general, you'll notice that a second tab quickly opens and closes before the original container tab is completely restored. This seems to only happen when you have a single container tab opened and doesn't occur when you have multiple containers. I couldn't reproduce this behaviour with a default container either, so it seems this is container specific.

Example: https://youtu.be/kuWqWRIcF6E

STR:

* install the latest version of m-c
* select "Show my windows and tabs from last time" under about:preferences#general
* open a personal container via file -> new container tab
* once opened, load gmail.com and close fx
* re-open fx and you'll notice that for a split second, fx loads two tabs and quickly closes one

It looks like session restore is creating a non-default Container tab and putting it first for a split second.

Why?

I've attached a screenshot from the video in comment#0 so it's easier to see the problem.

I couldn't reproduce this anymore with fx55.0a1 after several attempts. However, it's still reproducible with fx54.0b12 and fx53.0.3.

Using macOS 10.12.5x64:

* fx55.0a1, buildid: 20170530030204, changeset: 286f71223256 - couldn't reproduce the issue
* fx54.0b12, buildid: 20170529025116, changeset: 715d88d0bd82 - reproduced the issue
* fx53.0.3, buildid: 20170518000419, changeset: 1fe643b3421a - reproduced the issue

Clear a needinfo that is pending on an inactive user.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
