[Chromium][Opera] Ctrl+Shift+P cannot be used as a shortcut for opening pages in Firefox Private Browsing.

Description:
Opera allows users to set the Ctrl+Shift+P shortcut for opening pages in Firefox Private Browsing without notifying the user that it’s used for something else, when in fact performing the combination will open the Print handler.
As per the spec doc, the preferred shortcut for opening pages in Firefox Private Browsing is Ctrl+Shift+P, however, this combination should probably be changed to accommodate all browsers.

Steps to reproduce:

1. Load the Chromium Firefox Bridge v0.1 in the browser
2. Set the Ctrl+Shift+P key combination for “Open Site in Firefox Private Window”
3. Access https://www.wikipedia.org/
4. Perform the above key combination and notice the Print handler is opened

Expected:
As this appears to be an issue with Opera, I suggest a different default shortcut to be used to invoke the action of opening pages in Firefox Private Browsing

Actual:
Ctrl+Shift+P cannot be used as a shortcut for opening pages in Firefox Private Browsing as it opens the Print handler.

On macOS, Cmd+Shift+F attempts to toggle an option from the “View” tab on the toolbar, Cmd+Shift+E opens the Extensions Manager page and Cmd+Shift+P, as on Windows, opens the print handler.

So the desired shortcuts will not work in Opera and will have to be changed to something else.
