No support for Firefox containers

[jjdelc]

Short description

The container tab color isn't showing on vertical tabs. https://wiki.mozilla.org/Security/Contextual_Identity_Project/Containers

Steps to reproduce

1. Start Firefox Nightly with clean profile.
2. Install TST.
3. Open a tab in any specific container

Expected result

The tab should have a color hint indicating the container it belongs to

Actual result

Tabs does not have any indicator as if it was a "no container" tab.

Environment

• Platform (OS): Ubuntu 16.04
• Version of Firefox: Nightly 55
• Version (or revision) of Tree Style Tab: 0.1929170311...

Adding that when a new tab is opened from a container tab is does not open nested but parallel ignoring the parent relationship.

It appears that, at least with the new "Containers" experiment available through Mozilla's "Test Pilot" at least shows the color hint below the tab.

Regarding child tab creation when inside a container tab, this issue is still present.

Environment

• Platform (OS): Ubuntu 16.04
• Version of Firefox: Nightly 54.0a2
• Version (or revision) of Tree Style Tab: 0.19.2017031101

I used the test pilot experiment but disabled it as it had very poor performance compared to the built in feature that's available in nightly.

What the test pilot does though is switch the color on the tabs to be on the bottom instead of the default (on top). It looks like this behavior makes the color tabs show.

In FF53 I saw the context color markers as a single pixel line to the left of the tab icon (tree on right side of screen) - but I no longer see them in FF54. This is on MacOS.

I couldn't reproduce this anymore, with latest development build of TST http://piro.sakura.ne.jp/xul/xpi/nightly/ on Nightly 56.0a1 20170615031719.

Update: I see the colored lines again on FF54/MacOS. Weird, but it seems to have resolved itself :/

Confirm that tree style tabs is showing container colouring on tab in FF Nightly, as well as the new tab link allowing you to select which container.

Appears to be resolved on my side as well.

TST 0.19.x is already obsolete, so I close this.
