How to prevent bare windows in Firefox and related browsers?
Found it: http://kb.mozillazine.org/Prevent_websites_from_disabling_new_window_features
In about:config find dom.disable_window_open_feature.*
There are quite a few entries here that correspond to the various features that can be disabled/manipulated. Here's the list:
- close: Prevents the close button from being disabled.
- directories: Prevents the bookmarks toolbar from being hidden.
- location: Prevents the address bar from being hidden
- menubar: Prevents the menubar from being hidden.
- minimizable: Prevents popup window minimization from being disabled.
- personalbar: Prevents the bookmarks toolbar from being hidden.
- resizable: Prevents popup window resizing from being disabled.
- scrollbars: Prevents the scrollbars on a popup from being disabled.
- status: Prevents the status bar from being hidden.
- titlebar: Prevents the title bar from being hidden.
- toolbar: Prevents the navigation toolbar from being hidden.
Setting these to true overrides the developers preferences.
Mozilla's online documenation for the Window.open() web API describes how to make changes within the about:config Firefox management interface that will help accomplish what you want:
menubar: Mozilla and Firefox users can force new windows to always render the menubar by setting dom.disable_window_open_feature.menubar to true
toolbar: If this feature is on, then the new secondary window renders the Navigation Toolbar (Back, Forward, Reload, Stop buttons). Mozilla and Firefox users can force new windows to always render the Navigation Toolbar by setting dom.disable_window_open_feature.toolbar to true
personalbar: Mozilla and Firefox users can force new windows to always render the Personal Toolbar/Bookmarks toolbar by setting dom.disable_window_open_feature.personalbar to true
titlebar: Mozilla and Firefox users can force new windows to always render the titlebar by setting dom.disable_window_open_feature.titlebar to true
close: Mozilla and Firefox users can force new windows to always have a close button by setting dom.disable_window_open_feature.close to true
Notably, the following preference settings already default to true and don't need to be changed:
dom.disable_window_open_feature.resizable
dom.disable_window_open_feature.location
Also, starting with Firefox 49 the following feature is on by default so the about:config preference has been removed:
dom.disable_window_open_feature.scrollbars
