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.

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 👍

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
