1649884 - dom.disable_window_open_feature.location is broken now

Status: RESOLVED DUPLICATE of bug 1507375

(Core :: DOM: Core & HTML, defect)

Description

[Synetech]

Attachment: Screenshot of FF78 with dom.disable_window_open_feature.location toggled, but popup window still having location bar

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36

Steps to reproduce:

1. Set dom.disable_window_open_feature.* settings in about:config to false
2. Create a popup window with minimal browser chrome

Actual results:

Popup window should have minimal browser chrome

Expected results:

Specified browser chrome is removed except for the location/address bar

The popup-window settings haven't worked correctly since 75. It would be nice if they were fixed so that I don't have to stay with 75 forever. :-\

This appears to be by design. See Bug 1507375

It's by design to break one of the settings so that it no longer works and no longer provides users with control over their own browser? What's next, remove the ability to grant sites permission to access the camera just because it MIGHT get misused? 🙄

Firefox is turning into Chrome. Unfortunately there aren't any other alternatives to resort to anymore, so I guess it's either stick with 75 or just stop using the Internet. 😒

dom.disable_window_open_feature.* was there because web page have been able to control each UI part visibility when opening a new page (tab, window, or popup),
and the pref is to allow/deny each feature.

Allowing webpage to do so caused confusion (bug 1506655, bug 1533749), and
this happens only on Firefox, among modern browsers.

bug 1507375 changed the behavior, and now it almost matches to chrome, safari, and previous Edge
("almost" because those 3 behave slightly differently), that web page aren't able to control each UI part visibility,
but can request either a normal window (or tab, depending on configuration), or a popup,
depending on the features parameter.
And when opening a popup, location bar is always shown, for security reason (like, to avoid phishing).

Now that each feature parameter is just a condition whether to open popup or not,
dom.disable_window_open_feature.* has no more effect.
