How can I make a small window with no toolbars or other chrome?

Question

I want to create a second Firefox window that is smaller and has no chrome (toolbars, etc), so I can use it for things like pop out videos or reference pages. I could just pop out a window and manually remove all the things, but then this affects my main window next time I restart Firefox.

Are you using the javascript method window.open() to create the popup? If so, you could try the features parameter.

Note that by default, Firefox preserves some features, but you might be able to let those go by toggling various settings in about:config.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''window_''' and pause while the list is filtered
For each of the preferences starting with
'''dom. disable_window_open_feature. '''
if the value is true, the script cannot remove that feature. If you toggle it to false by double-clicking, then your window.open() should be able to strip that feature. Unfortunately, this is not site-specific, so other sites also would have permission to omit those features.
