How to stop websites from suppressing menus

Posted

My email program (Yahoo webmail) suppresses the menus on the pop-up window to print an email. Therefore I cannot do "Print Preview" or adjust scaling. How can I stop if from suppressing the menus, or restore them to a window that has them suppressed. Usual turn-on-menu tricks (<Alt> key, <F11>, three-bar menu's options) don't work in this case.

Is this about hiding toolbars like the Firefox Menu bar in a pop-up window ?

There are various dom.disable_window_open_feature prefs to prevent websites from hiding specific content that you can set to true to prevent a website from disabling this specific feature.

  • dom.disable_window_open_feature.menubar = true

Maybe toggling this pref on the about:config page will work.

  • dom.event.contextmenu.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Maybe toggling this pref on the <b>about:config</b> page will work. *dom.event.contextmenu.enabled = false You can open the <b>about:config</b> page via the location/address bar.

Thanks, but doesn't help. I believe that pref stops sites from messing with context menus (usually right-click menus.) I do figure it's a pref somewhere that I can't find.
