1760259 - Disable session restore infobar for marionette tests, webplatform tests and geckodriver

Status: RESOLVED FIXED

(Testing :: General, task, P2)

Description

[Julian Descottes [:jdescottes]]

We should set the preference browser.startup.couldRestoreSession.count to -1 for marionette tests, webplatform tests and geckodriver to avoid showing the "restore tabs" info bar.

It can make the viewport smaller than expected which makes automated tests flaky (see Bug 1734034)

(not sure if Testing/General is the right component here, since this impacts several test harness)

If doable it would be good to have this change as part of the next geckodriver 0.31.0 release given that it's not clear how many tests this could badly influence out there.

We plan to fully handle this in Firefox and this should no longer block geckodriver 0.31.0
