• https://addons.mozilla.org/firefox/addon/disable-private-browsing/

I have already use this addon, but it don't works

Did you try the plus version as mentioned on that page?

• Customizable Shortcuts: https://addons.mozilla.org/firefox/addon/customizable-shortcuts/
• Key config: https://addons.mozilla.org/firefox/addon/key-config/
• Keyconfig: http://mozilla.dorando.at/readme.html

Thank you! And, what's happen if i delete this addon?

If you delete or disable this add-on or start Firefox in Safe Mode then changes made by the extension won't be effective and the shortcut keys will work.
