about:config
When you type about:config in the address bar of Firefox, you are brought to a screen listing hundreds of options you can update to customize your Firefox experience. about:config rightly comes with a warning that by modifying these options you may cause problems with your install; luckily the setting we want to update is simply a boolean.
在Firefox的地址栏中键入about:config ，将显示一个屏幕，其中列出了数百个您可以更新以自定义Firefox体验的选项。 about:config正确地带有警告，修改这些选项可能会导致安装问题； 幸运的是，我们要更新的设置只是一个布尔值。
browser.privatebrowsing.autostart
Update the browser.privatebrowsing.autostart setting, which defaults to false, to true. Updating this setting ensures that Firefox windows and tabs open in private mode. You will need to close and reopen your browser for the updated setting to kick in.
更新browser.privatebrowsing.autostart设置，默认为false ，到true 。 更新此设置可确保Firefox窗口和选项卡在私有模式下打开。 您需要关闭并重新打开浏览器，才能启动更新的设置。
