Works great, but please, add the option to auto-close (or not to open) the tab in standard (non-private) window. Currently, when I open a webpage listed in settings, it opens the page both in normal window and in private window.

Great addon, does it's job well.
Please remember to explicit allow the addon running in private mode, otherwise it will fail!

Maybe the developer can make the addon check whether you allowed it yet and if not advise to do so.

This addon is useful if you are using FF with DDG, it can be used to automatically open !bangs in privacy mode.

For me, on Firefox 96.0.3, this extension only works correctly if I'm on the first tab in a window when I launch a listed site. Otherwise the listed site opens in both normal window AND private window.

Very good extension, does the job perfectly. The invert option is really helpful to change the behaviour of the add-on and open everything that's not in the whitelist in private tab. Thanks 👍

Works as expected, except in the following edge cases:
When Pasting a link in the url bar it opens a new private window, but the link opens in the normal window any way. Same thing when opening a link from another application (pdf-reader, messagenger,...)
Also It should look for existing private windows rather than creating a new for everything.
But i like that it is opensource and keeps it promis

Good Idea but it doesn't work on FF79.0 and also looking in Github it seems not maintained anymore.
---- Following the reply ----
Yes now I see what you mean. Would be great to ask "add-on execution in private windows" permission during the installation if possible or make more clear in the documentation that this is a manual step.

However thanks it works as expected now.

amazing security, best there is however one caveat, it does not work with FF 71.0b4; i do not see a permission to run in private windows listed
