1961271 - Add unit tests for Bug 1959812: Defer session restore when Firefox is launched via a taskbar tab window

Status: NEW

(Core :: Session Restore, enhancement, P3)

Description

[Eric Chen]

The patch for Bug 1959812 has landed but it's not possible to write tests for it until the taskbar tab installation features are in the code base

:nrishel will likely be the one writing these tests, you can reference the following marionette tests I wrote for another taskbar tab session restore patch.

In order to simulate Firefox launching with a taskbar tab window, I think you can pass in the appropriate command line arguments to the marionette webdriver.
