Incognito This Tab Firefox Extension

Incognito This Tab is a useful extension for Mozilla Firefox browser. It enables users to quickly open the current tab URL in an incognito mode (called as Private Browsing mode in Firefox), and removes it from the browsing history. Install it from Mozilla Add-on gallery.

How To Use

Once you have installed it successfully, you would notice its icon on the toolbar, as shown in the following screenshot. Click on this icon to open the current web page in an incognito window.

Important: To use this extension, you need to grant it “Run in Private Windows” permission. Follow these steps to grant this essential permission to the Incognito This Tab extension. Without this permission, this extension wouldn’t work at all.

Change Settings

By default, this extension performs two tasks: closes the current tab after opening it in the incognito mode, and removes it from your browsing history. But you can change the default behavior, and set the extension to not close the current tab or not remove it from the history. This can be done by following the steps described in this article.


Keyboard Command & Context Menu Option

This extension also offers a keyboard command: Alt + I, which is much faster than using the toolbar button. If this command is not working for you, or you want to change it, follow this tutorial.

Moreover, you can also use the context menu (right click menu) option to use this extension. Right click anywhere on a web page, and select the option “Incognito This Tab” as shown in the screenshot below:

    There was an addon called “Private Tabs” which kept the tabs you privatized on the same window. If you could mimic that feature, that would be far more convenient than what you have now.

    Like the other two three commenters, I began using your extension after “Private Tabs” became legacy. I like your extension but I had to disable it. I’m looking for something that will incognito a single tab but still allow access to extensions like LastPass.

  5. Bill says:

    I have the same needs as other posters here and that is single window mixing both regular and private tabs. I don’t wish to use regular window and private window management concurrently. Thank you.

    I suggest a feature I use on chrome with another extension: automatic incognito tab based on domain (with regular expression if possible). A sort of blacklist.

    Super Add-on. Thank you! If you could offer it on mobile (Android) it would be extra great!

    It doesn’t seem to work in FF 67. After the FF upgrade it will close the current tab but not open it in a incognito window.

    The addon needs to be granted the right to be used in private mode. This is new in Firefox 67. The addon should have get this right by default on updating from an earlier Firefox version, though. You could now once switch between disenabled and enabled, then it should work again.

    This extension is very useful, but as of late it keeps reverting back to its default setting “Close and Remove from History (default)” at every browser restart, when I prefer the other option “Don’t Close and Remove from History”. Please fix. Thanks!

    Can you please change the icon to a more visible color?
    It is the same color as the background on the dark theme on firefox.
