1489927 - Opening Firefox in private browsing mode does not place the private browsing indicator on the window UI

Status: RESOLVED WORKSFORME

(Firefox :: Private Browsing, defect)

Description

[zlinkort]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0
Build ID: 20180905220717

Steps to reproduce:

Open a Firefox window directly in private mode with the "-private" flag.


Actual results:

A Firefox window opens that looks exactly like a normal (non-private) window.


Expected results:

The private browsing indicator/badge should appear on the UI, just like it does when opening a private window from a regular window (Ctrl+Shift+P).

[Muhammed K. Y.]

According to the MDN's page that lists command line options (https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options#-private) "-private" option opens Firefox in permanent private browsing mode.

Accroding to Firefox's support page (https://support.mozilla.org/en-US/kb/private-browsing-use-firefox-without-history#w_can-i-set-firefox-to-always-use-private-browsing) private browsing mode is different than private window. So it shouldn't look like private browsing window if you use "-private" option, if you want to open private window from command line options you should use "-private-window" flag.

So this is expected behaviour according to the support and developer documents of Mozilla Firefox and doesn't seems to a bug to me.
