Protocol private:

[niceboy76]

With Palemoon 26.5, the protocol private: was ok. Now I have updated to 27.1 and this protocol isn't recognized.

Error description in page :

Malformed URI: https://addons.mozilla.org/
Usage example: private:https://addons.mozilla.org/

Thanks in advance for your answer.

Best Regards.

This is likely because newChannelFromURIWithLoadInfo which is already exist in FF37+ throws an error if second argument (aLoadInfo) is null and FF<44.

That is, this was caused by fix for nsIIOService.newChannelFromURI() deprecation: #215.
Now should be fixed: 5df97c5

Also thanks to @JustOff!
